Have you ever been watching TV when someone says, "You know, this was originally a movie," and you didn't even know? The movie could have been long ago, while good TV shows run a long time and then re-run forever. I was impressed with the 1970 movie MASH, and didn't think a TV show could live up to it. I was wrong, and 40 years later, realized that the movie did not age well. There are other shows that were better -and reached many more people- than the original movie, possibly because of the people involved, or maybe because the concept worked better as a continuing series. Read about five of them at TVOM.
