I have to admit that this anime hooks you from the very first episodes and it is most definitely interesting to watch to the very end (maybe except a few episodes). However, the more you think about it the more ridiculous it gets. Characters are pretty typical for an anime (even if the main character is a bad guy, he's still a typical anime bad guy)... a bunch of weirdos for fan-girls to feast on.

The more I think over the plot the less sense it makes. A lot of things simply seem unnecessary and unreasonable. Actually, it's hard to find anything that makes sense in this show and some parts simply seem funny.

Basically, it is interesting to watch but I'd suggest doing it only once otherwise you might start hating it.
