Here are a few that are out of the way or not quite what it says on the tin:

Kaiba is a very dark, surreal cartoon piece with mind editing and swapping as a central plot device.

Space Dandy is a wildly varying sketch show disguised as a goofy space western.

Wonderful Days is a Korean movie with a terrible plot, but it's very very pretty.

Genius Party and Genius Party Beyond are collections of shorts, mostly Sci-Fi, from Studio 4C.
