I appreciate the fact that this anime has a memorable catchphrase that is short and sweet it's really fun to quote off of most other anime i come across, catchphrases are either memorable dialogue which are typically long and drawn out or a mindless shout of the name of some signature attack moves. i also am a big fan of just about any psychological anime. and this dude's psychological madness is very amusing and how he keeps using that catchphrase...that catchphrase, whose is it?.. i also appreciate that this anime is loaded with a lot of my personal favorite voice actors dubbing the characters.
my only complaint so far is they could've done a better job with the animation. the appearance of many of the characters look so weird.
