I liked the movie Serenity but I can only hope it will inspire some network to let Joss Whedon bring that series back - Firefly, that it. Whedon's strength is in TV shows more than film. Yes survivorship in general was and remains a major theme of the series. See if you can't rent Firefly at your local movie rental place if they have a TV section. The show was cancelled before the end of the season but there is some hope among us afficianados that somehow Whedon will be able to bring it back.
Survivorship and surviving with one's morals intact. Watch and see.
