The movie gets a high rating because I sat in the theater with my jaw on the floor the whole time! The idea of shooting an entire film in blue-screen and then building everything else (all the sets and scenery) digitally is pretty radical, but the cool style of this movie really pulled it off. Everything has a 30s-40s feel to it, and looks just like it popped out of a science fiction comic book of the same era - giant robots, secret laboratories, dinosaur creatures, and tons of awesome technology. Truthfully, anyone could have acted these parts - they really didn't need stars like Gwyneth (but she was nice to look at anyway). I loved the amazing machines like the submarine airplanes and the floating aircraft carriers, and I had lots of "wow" moments when they would come upon the next gigantic set piece! Along with all this cool eye candy, they managed to put some funny dialogue in just the right places (I won't say there was any real character development, though). This is definitely a movie I would like to watch again, just to enjoy all of the amazing details. I don't think CG sets are the "future" of film-making, but for a story like this one, it was the perfect medium.
