Orson Scott Card says it's the best sci-fi movie ever. http://www.craigberntson.com/blog/2005/10/serenty-now.asp

>I just got back from seeing Serenity, and I must say it was great. The best movie I've seen in a while. It's nice to see someone take a great show like FireFly, turn things up a notch in the movie, and still maintain the feel of the original series. Maybe this will cause the series to make a comeback. One can only hope. By the way, seeing the series is not a requirement for the movie, although it may help you appreciate the characters more.
