Consider it a very mildly positive recommendation.
The game itself sure deserves to be played as the cult classic it is, but I assume you already know what to expect already and want to know if you should buy it on Steam.
Well, there are reasons for you to do it, and also reasons against.
To begin with, if you absolutely want to get the original game without resorting to piracy, I'm not sure you can get a digital copy anywhere else than on Steam, so you don't really have a choice. (Otherwise, you have plenty of easy ways to get your hands on this game.)
I must say, giving Steam users the opportunity to play and rediscover this great game series is commendable. It's however handled rather poorly. Basically, you will pay 10 bucks (do yourself a favor and buy the Classic Complete package if you're going to buy this game anyways) for an emulated version of the original game running through an outdated version of DOSBox, while there are a lot of source ports doing hell of a better job for free.
Now, I personnally don't have any issue with this (hence, the positive recommendation), and besides a few graphical glitches when I sometimes alt+tabbed in full screen mode, the game worked perfectly fine in this state. Judging by the negative reviews, though, the version of DOSBox it's running on isn't compatible with Windows 8 and requires messing with the game files in order to even launch.
Being an emulated game also means the max. available resolution is rather low, and it will upscale pretty badly if you want to go full screen on modern monitors. But you're not looking for HD graphics on this game, are you?
So be warned that while I recommend it from my personal experience, said experience may vary greatly depending on your OS.
If you lived in a cave the past 20+ years or are too young to remember audio tapes, VHS and floppy disks, you might need a brief introduction that will help you know what you're stepping into.
DOOM is mainly known for popularizing the FPS genre, along with Wolfenstein 3D, and, later on, Quake - to a point that the FPS genre was more often called DOOM-like and Quake-like than First Person Shooter. If you're an FPS lover who enjoys mindless fun and excessive brutality, games like Unreal, Duke Nukem 3D, or modern games like Bulletstorm and the new Shadow Warrior, you have to add DOOM and DOOM II to your list of played games.
Now, if you're coming from a modern FPS background, you're in for quite a shock gameplay-wise. No mouse look (not even looking up or down, which can be tricky when shooting enemies up on platforms or down a set of stairs), no crosshair to target enemies, no reloading, and very basic movements. You can only go forward/backward, turn left/right, and run - forget about crouching, jumping, walking slowly, or even strafing. Well, there is strafing, but it will require you to use turn left/right keys while holding another key, which is quite counter-intuitive when you're not used to it. This game actually plays a lot better with a gamepad provided you have the third-party tool to activate gamepad support.
If you still want to enjoy this game without going through the chore of adapting to the peculiar control scheme of the time, I recommend using Chocolate DOOM to play this game (check out the Steam forum to see how to install it). This source port is as close as it can get to the original experience, while keeping the comfort of some modern features like strafing and mouse look (you will only able to look left or right, but that's already something), and also fixing some lighting issues the Steam version got (some areas that are supposed to be pitch black are only a lot darker in this version).
I recommend the game itself, but as it goes for the Steam version, make sure it works on your OS by checking out the negative reviews before buying, and take the Classic Complete package because the asking price for the game alone is too high for what it is (the original game running on an outdated DOS emulator).
DOOM is a great game if you like mindless shooting, and going for 100% (all secrets/items/kills) and speed runs on each level is very fun for those who are looking for an extra challenge after completing the game once.
