Story:
FLCL is so crazy and random that the plot is totally irrelevant. Being only six episodes long, it lacks any sort of filler or rushed places. However, the series did not end so much as close itself.
Art:
The characters and robots are rendered in a smooth art style that really fits the series. It also has a South Park art shift. The backgrounds just blended into the work.
Sound:
The characters have voices that really fit them. The rock-out soundtrack is very fitting for the crazy atmosphere.
Characters:
Not very memorable, but still likeable and crazy, just like the series itself.
Enjoyment:
Want something short, sweet, and crazy? Then FLCL is for you! It's one of many anime with fewer episodes, but those episodes are high quality.
