1. Doctor Who Meets Firefly
Doctor Who: A long running BBC science fiction series, with loads of great episodes and a
few bad ones. It tells the tale of a renegade alien called The Doctor and his time machine spaceship the TARDIS. Over 50 years the show has featured an enormous cast, with eleven different actors playing the Doctor, and many more playing his ever-changing assortment of traveling companions. It also shows his long, never-ending battle with the Daleks, the most feared race in the galaxy.
Firefly: Arguably the most beloved science fiction series of all time, despite only having 14 episodes (only 11 of which aired). It shows us the lives of the small crew of the Serenity, a ship forever on the run from the oppressive Alliance, and taking any job that comes their way, whether legal or not. They must also try to avoid the deadly Reavers, humans who have been horribly transformed by a disease that people know little about.
The Crossover: It begins as a normal day for the crew of the Serenity, until they hear that
infamous sound. The captain - Mal Reynolds - is naturally wary of these new stowaways, while most of the crew accept them, seeing as they're all on the run. But the part that would be really really good? It would end with Daleks vs. Reavers, with the Doctor, his companion(s), and the crew of the Serenity caught in the middle.
