If movie companies offered a one-time stream for $3 or something, I'd pay to see a lot more movies. Hell, I'd probably end up seeing ones I liked in theaters, too.
A movie is going to be leaked. There's no way around it. They can do whatever they want, but it's going to get online. Why not cut that off at the head and offer a clear picture at a low price? The reason I don't go to the theater to see movies is a combination of time driving, cost of driving and seeing the movie (in both time and money), and mostly the hatred I have to jackasses who won't shut the fuck up during a movie.
I'd pay $3-5 to stream a legit movie a few days after it's in theaters, even if it was loaded up with DRM.
