The Good "Life"

Over the last year, I've turned into a bit of an anglophile. First it was Doctor Who, next came Top Gear, and now it's the BBC Original Life On Mars.

There's a new, US version of Life On Mars coming out soon.
There's been a long list of British television shows that have made the trip over the pond. American Idol, Three's Company, Weakest Link....on and on the list goes.
The basic gist of Life On Mars is that Sam Tyler is from 33 years in the future. He's not really sure how he got in the past, but he believes his body is in a coma, and his mind is tricking him into believing he's in the past, and that in order to get back to reality, he has to solve a set of issues.
The acting is great and each of the stories are well written.
One of the interesting points of the show is that once there was a conclusion, the show ended. Unlike other shows that start with a particular premise, like Life, once the original conclusion was reached, the show ended. It didn't find a new plot or premise to keep it going past it's prime, before it could jump the shark.
