yeah, Hellsign was a bit rushed at the end. i also have that impretion. and the end itself still confuses me. and i was mad that did they trade Alexander for Incorgnito? ill never get that -.- Alexander > Incorgnito x10000 times

and we still dont know what happened to the Police Girl (forgot her name XD)
Inuyasha was another case. it stoped abrutly. did Rumiko run out off avilable numbers of episodes or something? the same thing happened with her other anime Ranma 1/2. it ended right when Ranma's mother appered. WTF? luckly i have the hole manga

another case i thought the end was kinda of rushed was Chrno Crusades. after the episode when Rosette(sp?) finds her brother at fair, i though the story line was rushed untill the end.
another case is Night Walker. the couple last epsiode were confusing as well. so untill then Shido didnt remember his past when he was still human and sudently they're flashbacks of his wife and dauther? and how Kain convenced him to become a vampire? i dont get that one -.- still the last episode was my fav xD
