I wouldn't kill off either. Sure, often they work out badly, but sometimes you actually get good results. Silent Hill for instance, while the movie may not be that faithful to the games, it had a lot of depth to it and a legitimate point to make about the Judeo-Christian faith. Sure, a lot of people didn't like it, but I like it when a movie has something to say.
And while I'm too drunk right now to think of a movie game that worked out well, I'm sure it's happened before, and even if it hasn't, I'm not willing to give up on the hope that some day there might be an awesome movie based game.
