Fun Times.
One Piece - This is at best what I'd call... a poor series. The art style and action and everything about the show points towards slapstick and comedy. Which is fine, and when it sticks to being silly, it's fine. Great even. But the further it goes the more stupidly dramatic it gets. With character deaths of people who did nothing supposed to be big and momentous... Until you realize they're just pirates and all that means is a pirate is dead. Who cares. I sure don't!
It doesn't help the big battle thing that happens before the time skip is with a bunch of characters you barely know anything about, and so means nothing. Ace has no story to him at this point, and all the develop we do get of him is, "Onii-san I love you. Whitebeard Sensei I love you. Blackbeard I dislike you for pirate justice." Or. Something. And we're supposed to care about him, which is unfortunate, but he comes back with blond hair and a swanky hat and is at least cooler looking.
Bleach - Unfortunately it's boring. I was okay with it up until we saved the princess in the tower arc. (Rukia) I could never watch the series or read the manga for very long.
Death Note - Mary-Sue the baddish good guy. I actually liked this series until I saw Code Geass. Which having a similar protagonist, Lelouch suffers a lot for what he's doing.
Gurren Lagann - Mn. I didn't like the changes from OVER THE TOP WACKY TO let's look at this creepy underground complex where everything just slows down, THEN WE FIGHT A GIANT BATHTUB AFTER THAT. Also the series kinda burnt out for me on that. Not bad, but, it couldn't keep my attention.
Neon Genesis Evangelion, or whatever the thing is called. - Thanks fan-base. I couldn't get very far because of that. Also someone showed me a later movie before fully getting into the series and bllehuughghhdh.
Code Geass R2 - Yeah, went off the deep end and got too over the top.
Sword Art Online - It's like Twilight, WITH VIDEO GAMES. Bad characters, bad romance, and a whole lotta stupid. Honestly it wouldn't have been so bad if I didn't know about .Hack, particularly the GU games. (Though that third one got kinda weak with making Haseo so... bland.)
Naruto - Kyuubi dad to completely undermine all the work that Naruto did to get to that state. Fucking lame. I dropped it there, and kinda just checked in again for the ending, so there's that. It has more problems then that, but, I could hang out with it until that point where I could just not care for it any more.
Darker Then Black - Like. Episode 22-25 or something were so boring I dropped it, and I couldn't go back to finish it for the last episode. So. There's that.
