Sometimes I wonder how any series on MAL gets anything below 7.00 score.
Rosario + Vampire is a fine example of a manga which suffers from wrong tagging.
It has ACTION tag, but all the action is done in the first chapter, and all the following chapters are reenactments of that one fight. Oh wait, the villains were different each chapter, so there's that. Honestly though, I believe there's no lower low for action manga.
It also has COMEDY tag, and I don't remember laughing, smirking, or reacting anyhow beside cringing at hearing Tsukune point out ONCE AGAIN at the beginning of the chapter that "moka, while a cute and pretty girl, actually is a... VAMPIRE!" .This is the moment when retarded kids are suprised at the big font, since even they caught up by now who moka really is. Anyway, back to comedy. THERE's NO COMEDY, STUPID.
Well, if there's nothing for people seeking action, or wanting to laugh a bit, maybe FANTASY, magic or paranormal in general fans will find something worthwhile? WhaaaaaAAAT? You already know I'll say fantasy here is shit? c'mon now, let me at least elaborate! So. From this manga, I've learned that witches are actually monsters. AND lycanthropes are monsters also, not diseased/cursed/whatever humans. The werewolf form is their real shape. Yup. Bullshit explanations of phenomena taking place, ways new monsters are introduced and explained(half of them are, of course, one-time appearances of bully monsters, and the other half: the bullied monster girls, whom tsukune rescues by siccing his faithful vampire-dog at the bullies, and the girls fall for him because of his selfless heroism. oh, that's the harem tag done as well, i guess), and overall the understanding of mythology is so pathetic it's like listening to japaneese speak english.

There is only one tag that I'd let this manga have, a GARBAGE tag. It'd at least prevent the people looking to read something interesting from trusting the score entry in question has. If this trash gets GOOD/ VERY GOOD score as a MEAN from all the deadbrains AND people angry for wasting their time(the unlucky ones money), then anything can get 8.
Once again, if you didn't catch it. This manga is trash. And moka is a... VAMPIRE!!!
