A great film to watch, so when is the sequel, coming out, all ready?

I loved this movie! It came as a total surprise to me as I found it on HBO one afternoon and did not expect anything other than something mildly entertaining way to spend a rainy afternoon.  Boy was I taken by surprise!  It was not only an interesting story, but was dramatic, action packed and very funny too--I think the humor sold me!  I never saw the TV series it was based on, so, coming in cold, I found it a great movie if you like the sci- fi/action/thriller genre. It was still easy to understand despite not knowing the characters from the TV series.   And, Nathan Fillion is a great actor, could have hammed it up, but played his flawed Captain role just perfect!

More, I want MORE!!  Lets fire up the old story board and make MORE of these films!  Please????
