FLCL was insane. But there was sense to the insanity. This was a crazy sci-fi fantasy take on male puberty, and that was where a lot of its power was from.
The moment you switch sexes, as this one does, you lose the subtext. This time around, you've got a group of seemingly uncomplicated girls one of whom has something going on (annoyingly, she is so similar to one of the other four that I kept losing track of which was which).
The girls bland adventures made up most of the first episode, and it was all less interesting than the setup for the original. The crazy fighting girl is fun in her brief moments of screentime, but overall, there's just no there there. I just watched the one episode, and see no reason to watch a second.
