Alex is shot in 2008 and ends up in 1981, she follows leads that cases open up, believing it will help her find her way back home.
Well, after watching Life on Mars I didn't like the idea of creating a spin off that quite frankly may have failed, it didn't. I couldn't be sure weather or not it would be the same, without John Simm and the loss of the 1975 era.
Ashes to ashes is a great show just as Life on Mars was, the stories practically pull you into them as you try to figure out whether she'll get home or not. You've got to love Gene Hunt's policing methods.
