It's rare, indeed, when I go to a theater and when I do, it's the local Laemmle cineplex because at least it's decent. Decent, mind you, not really good.
What I get from my simple two channel set up with my OPPO blu-ray and Samsung plasma runs rings around anything I get at a movie theater. Sometimes I just have to see something but every single time I go, the picture is so-so as well as the sound.
The state of the art has progressed to the point where what you can get at home easily rivals, and betters, anything you can get at a theater. It's the way of the world my friend.
All the best,
