Up front, I like Scalzi. Not just a good Twitter follow but I really enjoyed the Old Man's War series. I remember seeing Redshirts and thinking it would be a good read. So, here goes: It's an enjoyable, fast-paced read. Definitely something you can finish on a lazy afternoon. The characters are engaging with quick, witty dialogue. The premise is great: what if background characters on a sci-fi show became self-aware and started questioning things? Why does the navigation station always explode during a battle? Why does a super-advanced starship pitch and yaw like a 1700s frigate? Why is one character always injured to the point of near-certain death, EVERY TIME, but then recovers? And why would people continue to join a military service that kills off 1-2 new enlistees on every away mission??? All these questions are answered in a wonderfully written story that also does a send-up on hacky sci-fi cable writers. It's light throughout, but has its moments of drama and a satisfying end. My only wish was that it was longer, or that there was a second. It's worth the time and money.
