I definately prefer the more Western feel to the series. They kinda cleaned things up and pushed the scifi bit more.. It works and makes for an incredible end for the series. The series just seemed more down-to-earth is all. I'm not a big sci-fi buff really and that's what drew me to the show. The blatant lack of sci-fi elements. But, like I said, it certainly doesn't hurt the movie to have them. Just a matter of personal taste. It's still Joss Whedon at his spiffiest.
