I have my own Movie rating system.

If I think I am going to like the movie, I will go out to the theater. Then I will wait for the special edition DVD.

If I have an interest in the movie, but don't really feel the desire to go out, I will wait for the DVD and if it's at the right price I will buy it.

If my interest is less then I will wait for it to come on TV and if I just happen to be bored when it's on I'll watch it.

Going to the movies is a treat for me not a necessity. When making the final decision it is one with regard to time, everything else seems secondary.
