I like Shrek 1 and 2. Pulp Fiction is a classic.Shrek on 4k - great fun. My favourite animated film I think, with Toy Story 2 and Up hard on its heels. Definitely a worthwhile step up from blu ray, though I doubt I'll be bothering with any of the sequels - Shek 2 is passable, but the returns were diminishing already.
Still, Pulp Fiction has a UK 4k release date for December - that'll be on my Christmas list.
