Just for the record there are two editions available of Coraline on Blu-ray - one has '3D' in a bubble on the leftmost side of the package and states that glasses is included, and is the anaglyph 3D version (i.e. a poor substitute for real 3D). THIS one (the one with 3D written in a bubble on the right side of the package and with 'Blu'ray 3D + Blu-ray' at the top of the front cover consists of the Real 3D version (i.e. you need proper 3D TV with compatible glasses, 3D Blu-ray player, and v1.4 HDMI cable) AND it contains the conventional 2D version which plays on any Blu-ray player, plus extras in 2D. Therefore if you're going to buy Coraline this is the version to get - you can watch 2D now and legitimate 3D when you buy appropriate equipment later on.
The image quality is stunning and highlights the beautiful details of the models used for the film (this is stop motion for the record), plus there's about an hour worth of extras. Great disc of a highly imaginative film that is okay for kids but features a few darker moments that may exclude it from the pleasure of much younger viewers. As an adult I enjoyed the film. Henry Selick (the director of this and Nightmare Before Christmas) is a truly talented person with fine understanding of animation.
