I totally agree with C3PX. The River on the cover of the movie, while not only being far too prominent when Mal is the main character, looks nothing like her. They went really heavy on the eye makeup while the "real" River has a much more natural look (thank goodness). It seems they were just trying to sell sexy.

And, yeah, as I've said before, Firefly is a great show. I disagree that the western motif was overused. I thought it was great, and I was disappointed that Serenity was overpowered with sci-fi without enough western to balance it out.
