Ugh, it seems to me like every show is eventually going to be turned into a movie. I could barely sit through the "Beverly Hillbillies" movie. I haven't watched some of the newer sitcoms in a while since I have become addicted to reality shows , but I can definitely think of a few that were already made into a movie that should have not have been:

Dukes of Hazzard : UGH

The Flinstones: Now this one takes the cake. I couldn't watch it in its entirety, although John Goodman really was a good choice for the role as Fred.
