Decided to give Community a go - gave up after 5 episodes. A couple of chuckles along the way, but just didn’t find it very funny at all. Disappointing.
Community's first season doesn't hit it's stride really until episode 9 or so - the fifth episode if the first one it shows signs of how weird it can become (with the scene in the swimming pool) but it does not do it particularly well; episode 7 does it better, but then episode 9 is great.
For my money, from about that point, until the end of season 3, is up there with the greatest runs of episodes of any American show EVER, not just comedies. So so many all time classics.
