My only objection to this is if XII was made with 3-D as an afterthought. Movies that do this as a cheap attempt to cash in on the 3-D craze after they've filmed tend to do pretty badly in terms of quality. Films that were made with the intention of 3-D from the start and take into account its properties tend to be fairly well made films (Avatar and Tron: Legacy, though admittedly both are pretty weak in the plot and character department).
