Life on Mars Episodes

I was so disappointed to find that once again I enjoyed watching a TV program, "Life on Mars", that had been slipping in the ratings. Once again ABC is pulling the plug. The last show to air will be April 1, 2009. What ever happened to letting it run a while to see if it finds a fan base. In the good old days, some TV programs ran a couple of years before they found a fan base and they ended up to be a big hit.
