I kinda guessed on a major plot point even before reading Ebert's review where he spoiled the shit out of it (he and a couple of other critics as well)... just pay attention to the commercials, take note of who is and isn't prominently featured, and voila... it also didn't help that during one of the making ofs Vin mutters a line that pretty much gives away the reason for the movie...

Anyway, I enjoyed the first, was lukewarm on the second one, conveniently missed the third, and will probably see this one... maybe in Hollywood with this newfangled technology that they're implementing for this film at the Chinese:
