I've seen it get plenty of criticism, much of it which in my opinion is unwarranted. I mean it's kind of understandable to be put off by the very frequent strong language but you can look past that and see the genuine entertainment the show has to offer. There's a weird sort of charm to it. I know that a few of the characters are basically just stereotypes but to counter that there are other original, interesting characters that give you more of a reason to follow the plot. The plots aren't the most in-depth but they do enough to consistently keep my attention. Also Brooklyn 99 has been cancelled one or two times and look how good that is.
