At the moment, of the 1,200+ films in the the Criterion Collection, four are animated (if you count Akira, which was only on released under the label on laserdisc). I think that a home video publisher that purports to focus on "important" films shouldn't be ignoring one of the most vital forms of storytelling in the medium.

All of these films either have not been released on blu ray or have a crappy one. I consider each item on this list to be socially, aesthetically, or historically important or just really good.
