There is a lot to like about Redshirts and John Scalzi creates an interesting meta-universe that gives a backstory to all of the disposable extras the filled many an episode of Star Trek. The book pokes fun at a storied television franchise and goes from silly to absurd as the junior crew members do what they can to avoid going on away missions. These crew members are more savvy than the original redshirts and they fully understand their odds of returning from an away mission when they go down to a planet along with more important ship personnel. Seeing things from the perspective of an "extra" is somewhat unique and one inside joke after another keeps things entertaining.
