Only thing I didn't like is them changing character origins. That should make it interesting to see how other characters are changed (Raiden the god of lightning and Goro half dragon half human). I like the whole concept behind it though and thats rare for me when I'm such a big fan of something. I don't like change, but this may be for the better as a movie.
Hopefully this means a game (not a game based on the movie) will be released around the same time with all the hype.
