A tad more violent than it needed to be, but this was a great continuation of the Firefly story. It answered many questions from the series and made the movie even more enjoyable. They pushed scientific possibility a bit far - but you're so busy enjoying the story and numerous surprises that you'll only realise it much later after the movie. Having seen the full series and movie now I hope they find a way to continue the story. If you enjoyed the story and humor of the series, you can't go wrong with the DVD.
