I take back what I said about Shonen Jump. About all they ended was Dragon ball. I totally see them milking Naruto, Bleach and One Piece to death. (Already doing it with Bleach. Tite Kubo was out of ideas like last year.) Also, Gainax was guilty of this. Evangelion's ending almost started a riot.

With the movie acting as an apology to the fans. (That's not even mentioning Kare Kano.)
Of course the worst of the worst is Suzumiya. First season was 14 episodes played in "We just threw a dart at a number and that's the episode we are playing now. Also, we are @#$%ing drunk." order. Then season 2 came out, for which they said was 28 episodes. But forgot to tell fans that included the original 14 in chronological order with new episodes mixed in. Plus, Half the new episodes where the same damn episode with minor changes. Sorta a Groundhog Day deal.
About the only series I can think of that did end, pre GitS|FMA, with something remotely satisfying was Trigun. And even that seemed a little rushed.
Tenjou is alright, I didn't understand the story later on it got pretty convulted and weird. The artwork is incredible and the fighting is over the top. (Like most manga)
There's very few manga out there that I absolutely adore though, so maybe I'm just picky. (Then again I hardly read the stuff these days)
I still read Bleach, even though Kubo is trolling his fanbase hard now. (Apparently, Aizens master plan over the span of 400 Manga chapters was to turn into a giant god damn condom...), Battle Angel (Rebooted into Dragon Ball Z apparently. Still awesome though.), Beelzebub (Shonen Jump manga that parodies other Shonen Jump manga by shortening what should be 50 chapter long battles into a curb stomp or, in one case, the main character walking out of the story arc altogether.) and Sasameki Koto. (Lesbian Schoolgirls. You really can't go wrong with that.)
Everything else is a gigantic chore for me to go through. I usually just watch the anime to get the general idea.
