As for anime, Big O, the third season was cancelled so we were left with a horrible, horrible ending that answered nothing.
I think that probably wins my vote, too. WE HAVE CAME TO TERMS.
I kind of disagree with Berserk and would've liked it to be a couple episodes
shorter than it was. If they were going to do the entire run of the manga, that would be one thing, but the way that they decided to cut it down to just the arc that the anime runs through would've been a lot better and less WTF-inducing if they'd left the first episode out entirely and changed the ending, getting rid of all the supernatural crap. Yes, it would've made it even more different from the manga, but it would've made for a better show, considering they already left out the vast majority of that stuff anyway.
I
very strongly disagree with Elfen Lied needing to be longer, which seems to put me in the minority. I thought the show was amazing but was very underwhelmed by the manga. I preferred the way the show ended, and when I later read the manga and saw the stuff that continued on past where the anime/manga split, I was very disappointed. It probably didn't help that the artwork is less good than the show and the translation I read was kind of mediocre, but beyond that I was just really unimpressed by the general story ideas themselves. I have since decided to pretend I never read it.
Oh, wait. I know what
does need to run longer and catch up with the manga: the whole Tsubasaholic universe. The shows/movies/OVAs weren't always as good as they should've/could've been, but they definitely had their moments, and it was kind of a shame when those got abandoned.
