Hmmm. Well, in my mind, the main difference between in-theatre and at-home is the size of the screen and therefore the visuals. So. When you decide, consider that Dave McKean is the artist for the movie, and that he has the resources of not only computer generated things but also the Creature Shop. The visuals are gorgeous; though you do get a decent sense of this from the trailer, I believe, so if you haven't seen the trailer yet, that might be a good way to decide.
