This is the least good out of all the five games.
That said, I still choose to give it a thumbs up because it's fun to play as always, littered with pop references and horrible (great) humor.
However, the upgrades system exasperates me. Quite early on, you run out of upgrades... and because there's at least one this-or-that ramification I have three stars sitting there, uncomfortably, just there, useless forever. And I got MANY stars so fast because it's apallingly easy, in comparison to the other games of the franchise. In my first run, I got three stars on every level, except one, I think. Everything at first try. The towers are too good at times, and two heroes feels OP.
Be warned this game has the most underwhelming boss in existence, ever. Beyond easy to beat. Terribly disappointing. Oh, and the extra missions you get when you finish the main campaign? Way harder than the boss.
Boo.
On the positive side, I really really enjoy having so many towers to choose from. But not much more. If you're a casual player, I guess it's okay. But honestly? Huge fan, veteran player expects better.

good game

can't wait for the new dlc! Fantastic tower defense game<3
