The Magnificent Seven

The Magnificent Seven is a program based on the five-movie series (but mostly the first two) from the 60's and 70's, which was in turn based on the 1954 Japanese film "Seven Samurai" by Akira Kurosawa.
The Magnificent Seven was canceled by CBS after the 1997-1998 season, but was later renewed thanks to a large internet campaign to save the show. The Magnificent Seven was canceled halfway through its second season run, but thanks to fan support CBS agreed to air the remaining six episodes. Unfortunately ratings were so low, CBS was only able to air two of the six before canceling the program again.
