I must be the only one here, who doesn't think Fooly Cooly's humor is funny. Yeah some episodes are entertaining to watch, but I have yet to laugh at an episode.
I don't think it's very funny, but I do think it's amazing, it premiered when I was 14 so it was pretty great timing as I felt I could identify with Naota's sexual tension with pretty much any girl that gave him the time of day. On top of that,I find the overall story fascinating, I must've seen the all 6 episodes like 30 times at this point, and I still think I discover new little things on each play through. I've got a great understanding of the whole story, but I still feel there are aspects that I don't quite fully get. And the manga is even tougher to follow. Let me also say I am not a big anime fan,it is not a medium I have seen much of, but my God, FLCL changed my life, it is by far the best anime I've seen and at only 6 episodes long, there is no reason to not give it a chance, it's all steaming on Netflix too.
