I'll be curious to see if others chime in.
This was my first thought upon seeing the OP as well. I haven't been to a theater in years, and part of the problem is I don't know what I'd go there to watch.
I've been pretty explicitly told that Hollywood does not want to sell to me or my demographic by this point, and it's also pretty evident in the media that is being produced.
And the media I do consume, I don't really feel a need to see in theaters.
I feel bad, because I have many fond memories of going to the theater as a kid with my parents. With the way things are going, they may be long gone before I ever get a chance to replicate that experience for a family of my own.
