I absolutely love going to the theater, especially when I end up being the only one there. I slot out budget and days specifically for it. It's painful as fuck for me to sit there for a couple hours like that (nerve stuff), but it's always worth it. I don't do the iMAX stuff though - just the $10-12 tickets. Sometimes I'll go for the $14-16 RPX tickets depending on the movie.
The Regal here also has pretty good food now too at not-extortion prices. You can get a good chicken strip basket for $7.99, Hamburgers, and other stuff. I just stay away from the ridiculously priced popcorn and soda and bring in my own drink and buy the "real" food there.
I don't go *that* often, but I do make it a point to go see every Marvel and DC movie at least. Plus some others I just have to see in a theater.
At home I have a 60" Plasma and a pretty nice surround system with floor standing speakers and good lighting for movies, but it's really just not ever the same.
