Query: Review of Blu-Ray 3D release not the film.

This is a prime example of why 3D is having trouble taking off for home viewing. Dreamworks's decision to hold back so long on releasing this film on Blu-Ray 3D was almost as painful as the version we did finally get. Sure, it's great to have it in 3D, but with no special features, and only available at Best Buy it is almost insulting. The film is great and the best 3D I have ever seen so it's a must own if you have a 3DTV, I can only hope Dreamworks wakes up and gives it the proper release it deserves.
