I went to see it last weekend. And it wasn't worth the money. Mind you, it's an enjoyable action movie remake of Disney's Pocahontas, with hints of Gorillas in the Mist and any movie about dragon riders, and to top it off a touch of space marines. But as mentioned, the plot is wildly unoriginal and totally predictable, which largely spoils the movie. The soundtrack is horribly uninspired. And the 3D effect does not add anything substantial, making the increased price tag quite annoying (and it was already more expensive because it's a longer movie).

(Oh, and I really like the Ewoks. And I've never had a problem with an entire population of primitive savages overwhelming a technologically superior force with far fewer numbers. It has happened numerous times in human history, so why not.)
