I wish we had a cheapo theatre here :/
I used to go alll the time, by myself. Just to see the movie though, because I love movies. There is only one in town, and it is in a rather large mall, but they are not hurting for business. Best Buy is the king of local electronics despite online shopping being superior (plus you don't have to deal with the poo-head morlocks that work there (take that language filter!!)), tech types will travel a bit to goto more specialty stores (I don't think you guys have Fry's electronics out there?) but Best Buy beat out the competition because there will always be people who go out to go out. People get bored, they have cash burning a hole in there pocket, they will always pay to go to movies.
That said, you are correct for the select amount that have an actual home theatre. But it has to emulate the movie experience properly. I've upgraded my setup... 4 times. From regular TV. to a backlit HD monster, to a smaller footprint LCD, to a projector, and now to a 3d projector. The first upgrade I ever got was surround sound. I would say this is exactly why -I- personally don't go to the movies.
But my brother for instance. He isn't want for money, and he has an HD TV... because I gave him my old one. He still goes to the movies with friends, and he comes to my house for 3D movies. People go to what is available to them. I think you'd be surprised at how few actually go all the way to get those experiences on their own. The typical consumer isn't aware, or is unwilling to believe that a home theater is an actual option.
I think that animated movies should have a 3d option. It might be cheaper to make them 3d, but they become full on stereo 3d, which is much better than post process. Of course the ones made to be 3d are obviously better (How to Train Your Dragon) But it's nice to have the option. Remember, you don't have to go see the 3d version. I agree that the novelty has worn off, but I still want the option to be there. Perhaps people mistake this as 3d being a waning fad, because individuals who don't want the experience have stopped going?
