Producer David Shore (HOUSE), who is heading up the remake, says, "It's one of the shows that made me want to become a writer."
Hmmm...then why don't you use that talent to create something new?
Remakes have their place...I certainly watch a fair number of movie remakes, and it can be interesting to see different takes on the same story.
However, I think modern Hollywood too often uses old material as a crutch and views a familiar title as something which will be easier to market.
In the case of THE ROCKFORD FILES, there will only ever be one Jim Rockford, and I suspect James Garner's legions of other fans will agree with me.
