First let me start off by saying that I have the following 3D movies:
Cirque Du Solei-Journey Of Man(Imax)
The Lion King
How To Train Your Dragon
Harry Potter and the Deathly Hallows (1 & 2)
Journey To The Center Of The Earth
Under The Sea (Imax)
And my prized movie that blows them all away for 3D is called:
A Turtle's Tale, Sammy's Adventure
The 3D in this animated movie is beyond words. It blows away every one of the movies listed above and puts Avatar to shame. I just can't tell you how incredible the 3D is. The whole movie basically takes place out of the screen and in your living room.
If there is one and only one movie that was ever made to Demo 3D, this is the one. It's 3D done right! It's also got a DTS Master Audio Sound Track.
Yes, some of my other movies listed above do have some good 3d moments but Sammy's Adventure is consistant from start to finish. It's just plain awesome. This is the movie that would make me go out and buy a 3D TV if I didn't already have one. Not many movies can make you feel that you're actually part of it...this one will! You must own this one at any price! It is worth it.
Of all the 3D movies I have seen, including Toy Story 3 in the Theater (not very impressive), A Turtle's Tale, Sammy's Adventure is hands down the best I've seen yet. This is my new reference material.
