I like both versions. I plan to take another look at the original animated one as part of my consideration of the pre-show for our attraction. When it comes to fantasy, I think I would tend to prefer the more realistic version if it is well done, versus the animated. It just come to "life" more for me, and I definitely think this was well done. Seeing it in IMAX 3-D made for a special experience. Even the end credits looked beautiful, and our audience mostly stayed through them.
Having said that, I'm thinking for our theme park project that we should rely on the look of the animated feature. It's a question I've been thinking about even before seeing the new movie.
