I don't think that's it. I think that you have to start with "theater worthy" franchises and most tv shows, particularly those in sitcom format, just aren't up to snuff.
I personally liked the beverly Hillbillies, but I wasn't expectign it to be much more than a glorified "made for tv" movie. Which is essentially what it was.
Starsky and Hutch failed because Owen Wilson and Ben Stiller were in it together. It's funny, they are competant actors apart, but you put them together....
The Addams Family took virtually nothing from the tv series, and in it's case I think that's a good thing. Afterall, the Munsters is practically the same show and it's made for tv movies have always been just awful.
The brady bunch just didn't work for me. It felt like the saturday night live (and other comedy troupes) parodies that were done years earlier. I thought the approach was brilliant, and it was the best possible way to do it, but you can't polish a turd.
The Dark Shadows film is going to be terrible. From what my mom tells me, that show was like the 70's version of Heroes.... a little campy, but hugely popular. I remember the failed reboot of the series in the 90's and thought it had a lot of potential... but NOT as a comedy.
I haven't seen the Stooges yet but I'm not suprised that it turned out well. Physical comedy is pretty hard to screw up and the stooges are timeless. I'll be saving it for a rainy day. You've also got to remember that the stooges have been sitting on a shelf virtually untouched since the 30's and 40's. You get a lot more creative leeway when you are dealing with an IP that is that old and unused.
