We went to see
Coraline
in 3-D, and it was subtly wrong and creepy in a suitably Gaiman-esque
way. The 3-D is beautifully done -- blended in such a seamless way
that you almost don't notice that you're watching a movie in 3-D, but
it brings real additional life and depth to the visuals -- so
definitely go see it in 3-D if you can.
I think the first segment of the movie, which is devoted to
world-building, is far better than the second segment, which is
action-oriented. The pacing of the introduction of Coraline's real
world and the alternative button world is slow and delicious, which
makes the remainder of the movie feel rushed, but overall, this is an
outstanding film.
Definitely go see it in a theater, in 3-D. It's worth it, and you'll
really miss the visual impact if you wait to see it on DVD.
