Absolute fantastic film
Saw Serenity at the weekend, along with my non sci-fi loving wife. Even she enjoyed it :)
You don't need to have seen the original series to get this movie, although if you have, it makes the story much more poinant.
I think everyone should see this, it has the same laid back feel as the series, and each character's personality shines through. Even though it is obviously an action movie, it is most definately story and character driven.
Will definitely be getting this out on video when it comes out :)
