Saw it in 2D today, and I have to say while it held up decently, 3D did help enhance the movie quite a bit. Interestingly, some things in the movie in 3D were just flat with no attempt to make it look 3D in the 2D version. For example, all the photos of the Na'vi that are seen in the remote lab are just flat photographs instead of the hologram ones.
