I don't wanna come off as defending any of this, but even 20 years ago I'd bring my own snacks or eat nothing at the movies, the stuff they sell was always considered overpriced. So I'd definitely skip the sodas and popcorn.

That being said, I don't go to theaters anymore either. I'd rather watch stuff from the comfort of my home, at any hour of the day. If I have to wait a few months for web/BD releases, no big deal. I have plenty to watch in the meantime.
