Rating this on the movie alone, I would give it only 1 star. It's a bad story and really boring. I only purchased it to see the 3-D version, using the special glasses that you must buy seperate. The 3-D effect is really good. Not as fully dimentional as the other DVD's available for the 3-D system, but still works very well. As with the other three 3-D Slingshot DVD's available, the sound is really good too.
Overall, the movie itself is poor, but the visuals (in 3-D) and the sound (DTS) is very good. I would recommend checking out the Ultimate 3-D Collection (which includes the glasses and the three other 3-D DVD's, that is listed at Amazon.com) before purchasing Ultimate G's.
