When Ratatouille was released this past summer, I thought it was one of the best animated films I'd ever seen—certainly finer than anything else in that category that could come along in the same year. I still hold Pixar's gourmet rodent near to my heart, but now, one week before the end of 2007, comes Persepolis (Sony Pictures Classics), a completely different kind of animated movie that, even more than Ratatouille, reimagines what the medium can do.
