TL;DR - Get the sequels, they're much better!

First things first: You may consider this more of a side-thumb than a thumbs down. Yes, I'm registering it as a negative - that's what you get for having a score higher than you deserve, game! Why do I feel this way? Well, let me explain.

You see, this game is a modern revamp of the ancient-era computer game, Theme Hospital - itself a sort of spin-off of a game called Theme Park, hence the name. Theme Hospital introduced silly illnesses, room-planning gameplay, the charming Tannoy Lady who makes regular (and often silly) announcements via the hospital's public speaker system, such as "Patients are asked to be patient." and "Patients are reminded not to die in the corridors~" ...This, in retrospect, was probably always the best part.

So! It's a side vote, after all; what does Two Point Hospital get right? Well, the Tannoy Lady, for starters. They brought her back (same voice actress, too, if I'm not mistaken) and wrote her some delightful new material. There are also a few different radio DJs who are apparently all voiced by the same man, and I have to say, I never realized. So, job well done there as well; they're a decently varied and interesting gang to listen to in between tracks of background music. The music itself works well too.

The silly illnesses can be somewhat amusing to read about, and some of them are visible as well (i.e. Lightheadedness, which causes the patient's head to turn into a giant lightbulb). The equipment and methods used to cure them are sometimes amusing as well, with some nice animation work. Credit where credit is due!

Now, sadly, we get to the bad parts. The gameplay, for starters. If you play this game, you'll want to use the Template function, and use it a lot. At each of many locations on your healthcare journey across the fictional Two Point County, you will be building the same rooms over, and over, and over again; so come up with one solid design you enjoy, and/or that is optimally space-efficient, and plonk down copies of it quick and easy when you need to.

If you do not heed this advice, most of the gameplay will consist of repeatedly attempting to decorate rooms that are... very uncooperative, a lot of the time, with the exact footprints of objects being quite confusingly shaped and often slightly larger than they have any right to be, making it a massive chore to fit in all the things you want to. Especially when your staff keep pestering you for a level 5 staff room, for instance - do they know how much rubbish you need to cram in there to get that rating up to level 5?!

There's also the way the game works. There's a clear priority divide between this game and myself; to wit, I feel that a hospital should prevent people from dying, as well as cure them; the game pretty much says "Well, you get paid either way, so as long as about half of them survive, you're fine." Yes, you eventually need to get your cure percentages and reputation up for some of the "star" (area completion and, well, over-completion?) objectives, but the thing is... by the time you finally have all the treatment rooms (which is a lot), you'll be the proud owner of a giant money factory and can buy whatever you need to win.

And then there's the training. See, when you hire doctors and nurses, they have a given ability level. They might be fresh level 1 med students with terrible diagnosis and treatment abilities, or level 5 consultants whose only flaw is how expensive their salary is. Higher level doctors and nurses have more skills as well, and as newer ones level up and earn promotions, they must fill each training slot with a skill in order to keep earning experience and general competence levels.
This does not work.
I mean, it does - badly - but the crux of the matter is this: While your doctors are training, they are not treating patients. They are not diagnosing or analyzing patients. They're just sitting there in the training room, and if you want to save a considerable amount of early-game money (and you do!) you'll want their colleagues to do the lecturing where possible, rather than an overpaid guest lecturer (your only option if none of your staff have the skill you want to teach).
So, you either let some patients get poorly diagnosed, riskily treated and quite often left very much bereft of life by incompetent doctors and nurses that were the best you could find or afford...
Or you let some patients run out of health and die of that instead, while you train your staff to be decently competent (or better).
You may be thinking "Why not just hire twice as many of everything, then?" Well, a couple of reasons.
1: Money. You don't have enough of it for infinite salary costs, especially at the start of each scenario.
2: Candidates. You have a limited pool of potential staff for hire at any given time, and it replenishes slowly, one at a time. If you reject one doctor because he reportedly is unhygienic, has all the wrong skills and drops litter everywhere, you have to wait for a new one to fill the available slot... unless one of the other candidates happens to fit perfectly. And of course, the new one might be just as bad, or worse. The flow of staff into your hospital is a trickle, which encourages training up your own staff, and also OCD and nervous breakdowns regarding their abilities and personal traits. And even if you hire every person on offer, you may not end up with enough staff to run the hospital while the rest are in training.

Granted, even if you manage to hire or train the perfect set of employees, we soon run into another brick wall: Breaks.

Your patients and staff all have needs. They need food, drink, amusement, a place to rest, access to toilets, and pretty things all around them all the time everywhere. Providing all of this in a rapidly expanding hospital is, to say the least, exhausting. The earlier scenarios are more manageable of course, but the fun really goes out of it around the time they make you build hospitals with all the buildings separated by yawning voids of time-wasting footpaths. Did I mention staff and patients all walk excruciatingly slowly unless they have special speed traits and skills? Well, they do, and it's galling as all heck.

So when your staff decide to take fifteen to twenty in-game days (which are about five seconds each, granted) off work to drink a soda from the vending machine, sit in the staff room sofa, go to the toilet, back to the staff room, ignore all the needs-replenishing things in the staff room as well as their work room, and then finally go back to the operating theater... after leaving RIGHT before a life-saving surgery, while the nurse assisting just sort of stands around rapidly running their needs meters down, waiting for the one qualified surgeon in the hospital to finish that break... and then the nurse goes on break as well, just as the surgeon is coming back...! Well, perhaps you begin to grasp the roots of my complaint.

Add to this some decidedly janky management controls, and you've got yourself a recipe for frustration. You can pick up staff members and drop them in a room to have them work there. Hypothetically. In practice, they usually go "invalid destination" and wander out of the room, bumble off "looking for work" after you just told them exactly where to work. Twice. Or thrice. And at some point, they do stay in the room and work, but the correct number of times to need to tell them that? Is ONE.
And remember those breaks? Well, when a doctor or nurse goes on break, they will leave their workplace and not return unless by chance. Even if they're the best person to work there. There's a policy to stop them leaving a room if idle, but that doesn't stop breaks, does it! So everyone is always in the wrong room. Maddening.

Mostly disrecommended. Get it on sale - if at all - and play only as long as you enjoy it.

The sequels are really cool, though! Those, I recommend.

I named my hospital "You Will ♥♥♥♥♥♥♥ Die"

The first 3 hours are good, then it gets very repetitive and stale. A bit to shallow for my taste.
