When the TV show Firefly never got rebooted, fans went to great lengths to bring about a sequel film titled Serenity. Since I already gave a character run down in my review of Firefly I encourage you to go my review to see it if you're interested. :)
Serenity picks back up on the adventures of Mal and his renegade crew on the ship Serenity. Once again assassins sent by the Alliance are after River Tamm and the crew is on the run. They soon find out though that the Alliance will stop at nothing to get River back. Along the way the discover a secret the Alliance is trying hard to hide.
This is a great conclusion to what Firefly started, though of course it would have been better if Firefly had just never ended! There are certain horribly heartbreaking moments that I won't give away but overall it is full of the same fun and sic-fi/western flair that was a hallmark of Firefly. One nice thing about serenity is that there is no inappropriate scenes in it as there is in Firefly, just some innuendo.
If you like Firefly you'll love Serenity too. :)
