I stumbled across a yaoi called Okane Ga Nai. I'm fine with yaoi, it's okay, but... but... it was... just... no. It gave yaoi a bad reputation in my book. Nothing can redeem Ayase. He single-handedly ruined the entire show. An extremely submissive, weepy blonde big-eyed pretty boy who can't raise a finger to defend himself and is probably the personification of the word 'uke'. The proportions also make me cringe. He looks like a kid compared to the 'seme'.
I don't like anime/manga that have an "unbalanced" element.
-Full Moon is okay, the main character, Mitsuki, acts a bit like a Mary-Sue in the beginning.
-Orange Planet, too repetitive of a plot where I lost interest in it.
-Somewhat of Fruits Basket (*Gasp!* How can you say that?!), It is Tohru Honda... I think she assumes the personality of Mary-Sue a bit. I expect flames but that is my opinion.
-Romeo X Juliet (Yes, the manga version), it was a slight dive into la-la-la land toward the ending where I felt some of the originality was lost. It has been awhile but that tree of life spirit thing seemed to be a last-minute put-together to make-up for the Montague and Capulet lovebirds to have the death scene. It gave me an unsettling feeling.
Those anime or manga that give a character too much "slack" to be a realistic expectation for their actions (ex: When the girl hits the guy for an honest answer and she is automatically in the "victim" category. Then the story revolves where the reader is supposed to sympathize with that. Nuh-uh. Too desperate. There has to be a give-and-take and it feels one-dimensional).
When an anime/manga does not have substance. I can not recall any at the moment.
I have to say... It isn't that Naruto is bad... It's just overrated and that Sasuke has become a gary stu. I particulary like Naruto, Alot. But I much perfer Shippuden. (Sakura is much stronger, since Sasuke is gone LOL) Well... Pokemon I only like a bit... Just becase of Darkrai.... he's bad ass.... Elfen Lied I liked because gore gore and more gore. (Natural horror fan) Soul eater has a good storyline but strange art blah blah blahh... Okay enough. Most of the "Bad Anime" is those that fandoms have been blown out of porportion. Bleach and Naruto are great examples. Death Note is still great. Hands down. (Sue me.) D.Gray-man I particulary like. I hate shoujo though. To be honest, my friend got a Tamaki Suoh cosplay from Ouran High School Host Club, and she dared me to watch it. I bled. or days. I am a shounen girl. Now leave me alone from all of your sparkly gay boys and your KAWAII DESU idiotic female leads while I go back to good ole' bad ass Alucard. Hellsing.
The stupid soppy romances with pussy girls who (even if they are SUPPOSED to be strong characters) cry and fall in love with idiots. God I can't stand them, especially if they don't have any humor or action or SOMETHING else in them.
