See my other comment, thought D was Bloodlust. Not bad but watchable, the original is head and shoulders above.
Right, Trigun wasn't bad. But I came from Cowboy Bebop at the time I saw it which was just way superior in any way. Both, the movie and the series. Check it out!
And, yep, not mentioning the classics like Akira and for me Ghost in the Shell (GitS: Innocence being not bad either, but the orginial is probably in my all time top ten movie list). GitS series was bland imo, couldn't bear watching it with the movie in mind.
Lot of people seem to love the Evangelion flics (not sure if there is also a series of that) but I couldn't get into it.
