Some observations: I enjoy historical epics too much. I'm surprised more animation didn't feature but ultimately they had to be absolutely exceptional to get in atleast in my opinion.
***Wizard People, Dear Reader was never properly commercially released, I'm not sure if it really counts but I do think it's a genuine stand-alone piece of art and comedy film. It's one of the funniest films I've ever seen
