The local club finished off an anime series lately which was about the most cliche and moe anime harem series ever. And I just spent about 10 minutes looking up the title of the damn thing.
It's called Asobi ni iku yo!
So you have your typical high school boy. And a horny 16 year old catgirl alien from a planet of catgirls hides in his house because her species of catgirls are at war with dog girls and both species have impossibly large breasts and wear little clothing. You have the clumsy ditzy catgirl. You have the tsundere bitch girl. You have the shy geeky girl. You have maids and loli. There's fan service and nudity that's blocked out by mini-robots. And in the end, while two girls are fighting over the main character, the catgirl says "Let's all be with him!" So the main character gets his own harem at the end of the series.
Predictable, cliche, and boring.
Then there's Puella Magi Madoka Magica.
It's a magical girl anime that just about everyone in one anime group claims is the best fucking anime ever, even being a magical girl anime.
I'll give it one thing: it's far from cliche or overdone. Main characters die. The series is more serious and emo than light-hearted. There's quite a bit of action scenes, and not "In the name of uranus I do the same exact spell I've done 50 billion times to kill you in one hit." The action scenes are in a parallel dimension that is done with a unique style of artwork.
But, considering my favorite character gets killed by episode 3, and all the emo-ness of little girls crying all the time because people are dying and bad things are happening, I just don't think it's all it's hyped to be. A great series, probably. Just not the best series ever like some people act.
