Roberta Smith in the NYT:

Not all filmmakers create complete and resonant fantasy worlds, rife with strange, sometimes frightening beings as well as mysterious movement, emotional suspense and uncanny detail. Fewer still are honored with extensive museum retrospectives that do these worlds full immersive justice, allowing devotees and neophytes alike to grasp the essence of their achievement and its evolution, strengths and weaknesses all.

But this is what the Museum of Modern Art has accomplished for the elaborate puppet-centered parallel universe brought forth by the experimental animators known as the Quay Brothers.
