This one is a DVD rental. Firefly was a series that no longer airs on Sci Fi. Sadly, I missed out on the series. I think the series would have been an enjoyable series but as far a movie I was disappointed. The movie relied on you having seen the series and left out the character development. The movie gets to a very slow start. It does end much better then it begins. If your into Sci Fi and aren’t looking for an engulfing movie but more of something to fill your Firefly needs in-between episodes of SG-1. “God’s balls your mad!”
