I bought this for our growing 3D blu-ray collection based on numerous recommendations from the 3D Facebook groups I belong to. Expectations were not too high going in, as I figured this was just another remake cash-grab movie, but it was much better than I expected. The villains are a bit over the top and the storyline follows the traditional "We've got to somehow save the (fill in the blank) before the bad guys ruin it" narrative, but it's still a fun ride. The lead voices do a very credible job of bringing my old childhood pals to life in an up to date, but reverent manner.
The 3D is where this movie really shines. The animated characters blend and interact seamlessly with their real-world counterparts, and the depth and detail is on a par with any other 3D release I've seen. And there are some truly hilarious pop-out sequences that had my wife and I laughing out loud.
I can see this becoming one of my go-to reference movies to showcase what 3D blu-ray is capable of to friends and naysayers. It's a no-brainer for the kids, but even adults will appreciate it for the details.
