Oh yes two, I forgot they killed the minister man as well. I personally loved the film and felt it uncovered much of what Whedon would have liked to in the show if it wasn't cancelled. Such as Rivers back story.
I couldn't stand it, it was your typical Hollywood epic action movie and it lost the space-cowboy motif that made the show so great.
I actually saw the movie first and thought it was okay. Then I saw the show and asked myself what the hell they were thinking with that movie? The show had this brilliant balance of theme, writing, and acting. It was so good that obviously Fox would have to cancel it. But the film lost it all.
