Just got back from the movie. Out of 10, I'd give it a 6.5 to 7. Not the best movie, but definitely worth watching.
For the lawsuit, I don't think it's going to hold much water. Whitewolf has the storytelling system, however, I didn't see much in the movie that was comparable to the WW system at all.
Style-wise, this movie was similar to Matrix, in that Matrix had somewhat of a greenish tint to the whole movie, and was pretty dark and pale in color, while this one had a similar style but more of a blue tint.
