I've watched a lot of anime titles, but I like to stick to films. I'll say two, one of which many people probably have never heard of, and the other I might crucified for.
The first is Neo Tokyo. I've seen a lot of films that attempt to be more art than story, but it was the equivalent of modern art; it was bland and tasteless, with it's only appeal being "strange". I had to really push myself to watch it.
The next is Akira. I can't fathom why everyone panders to this film so hard and how it "saved anime" in the 90's. I suppose it might have been good in it's time, but its one of the few animes I couldn't finish, and as of today, it's the only film I couldn't finish.
