"When they actually made the movie I had doubts about it from the beginning, and expressed them, and didn’t really get too far," King said. "Sometimes when people have made up their mind, the creative team that’s actually going to go and shoot the movie, it’s a little bit like hitting your fist against hard rubber, you know? It doesn’t really hurt, but you don’t get anywhere. It just sort of bounces back. And I thought to myself, Well, people are going to be really puzzled by this, and they were. So there was some of that problem, too."
If this is to be believed (I recall a number of pre-release hype statements from King), King should've tried to quash this project from the start (it's his material after all). Sony left the Tower in developmental hell for so long that I think by the time the ball got rolling they were just throwing default concepts at the wall (name actors, loud noises, cliche one liners) in the hope that they would draw some eyes.
