Hahah - I watched the movie too. They definitely upped the ante on the action scenes.
My only complaint with the movie was that some of the characters seemed off. The beginning movie-Mal seemed quite different the Mal at the end of the show. He had a few lines where he basically kicked off Simon for not "being one of the crew." Which struck me as odd considering he was always part of the crew before. And Mal also took shit from Jayne, which wasn't like the TV-Mal.
It also made me sad that Wash died. Like, more sad than I should have been. Haha.
Anyway, really enjoyed the movie. And good series overall. Sad that it never really got to its full potential.
Now I need something else to watch.
