Oh, the highly acclaimed Fooly Cooly. It's been labeled as a "masterpiece", something "special" "unique" "pleasantly different" yada yada yada. For an anime to have gotten this much praise then it should have been extremely enjoyable and in particular funny as it is supposedly meant to be a comedy(primarily).
Sadly, FLCL did not offer any but was a one way trip to hell the moment a certain character made a flashy appearance in the first episode.
STORY: There is absolutely no story behind this anime. It is just six episodes of disjointed scripts that attempt to fuse together as much genres as possible then injected with pointless crude sexual humor. It is as confusing as reading a Chemistry textbook upside down and going to write a Biology exam. It is not anything overly intelligent that one wouldn't understand but a very sorry attempt for a plot.
ART: A rather welcome aspect of FLCL. The art is unique and very neat while the animation is decent but nothing breathtaking.
SOUND: Another redeeming feature of the show.The music, as a standalone is nothing special but mixed with FLCL actually makes sense. It blends perfectly with the animation and just about managed to keep my sanity while being subject to the torture that was Fooly Cooly.
CHARACTER: This is perhaps the aspect of FLCL that is worse than the Story. A good anime has characters that you can connect to, ones you feel an attachment to, ones you root for, likable characters. The only half decent character in FLCL is Naota. The lot of em are either disgusting or detestable and very easily forgettable.
Now welcome to Haruko, my no. 3 most hated character in anime history only behind Shin in Gundam Seed Destiny and Roshio in TTGL. The introduction of Haruko marked the end of FLCL for me. A good description of her would be spontaneously annoying.
ENJOYMENT: I did not enjoy FLCL plain and simple. I have watched this anime an unbelievable 3 times because I kept telling myself maybe just maybe I missed something or there's is an underlying essence but NO, I only hated it more each time.
CONCLUSION: When there is a subject of controversy, you find things like
-One man's meat is another man's poison
-it is hit or miss
-People have different tastes etc
In this regard, FLCL is as polarizing as they come. It will be a love/hate relationship if you decide to brave the show. The good thing is you'll know which category you belong very early on.
