Serenity provides closure to the Firefly TV series. It can actually stand on its own (I think) but the experience would definitely be better if you have seen the series.
In the movie, the crew decides to find out what is behind the angst of River, the ship’s resident psychic. Hot in their heels is the Alliance who are after River, blocking their way are Reavers, vicious buggers straight out of Cannibal Holocaust. This situation leads to an action packed movie full of fighting: hand-to-hand combat, swordfights, gunfights, anf even ship-to-ship combat wherever you go. It is definitely more of an action movie than anything else. Still, it is a fitting end to a pretty great sci-fi TV show.
Rating: 4/5
