First off, I want to say that I loved this movie. It's got intense action sequences, a good plot,some humor, likable characters, fantastic special effects, hardly ever a dull moment,and oh yeah... it's a total babe-fest!!! I must confess I'm new to the whole Firefly universe.I don't watch much TV so I'd never even heard of the TV show. So until watched this DVD, to me,Firefly was nothing but a dumpy little American made car. I rented this movie with no expectations whatsoever; maybe that's the reason I enjoyed this movie so much. I can't speak for the fans of the series, but if you enjoy well-made sci-fi, then you'll love this cool little movie.
