I have a method to enjoy this kind of anime. I watch them as if I'm watching Power Puff Girls (PPG is far better than this though). You know, not for the deep plot, well-developed story or gorgeous and animative battles, but simply because the cute girls are there, kyun-kyun moe-moe all over the place, unharmed. PLUS: - Many lovely unique girls playing around to please the weeb inside of you. - Amazing cast. If you're into anime for a year or two now you'll regconize many familiar voices. Most characters are played by well-known and talented seiyuu. MINUS: - Well, shallow and boring most of thetime.
- Mediocre artworks, mediocre designs, mediocre soundtracks, mediocre pretty much everything.

This is okay, or maybe even slightly good to watch, if you don't expect too much and just want to peacefully pass the free time you don't know how to spend.
