Remember what I said about exaggerating the scale of difference? If you honestly believes this is the difference in the experience, you sound deranged.
Okay, sure, let's bump it up. Make it a bare concrete room with plastic chairs and a regular cinema system.
You're not going to see or hear the movie any worse, that's what matters right? What's a little uncomfortable seating. They'll get better seats in about a year.
Though if you have a question about a movie, all the leaflets are in the other theater.
If the movie's running in 3D, the glasses are also in the other theater.
Want to buy food? Concessions stand in the other theater.
Use the restroom? You know where this is going.
Basically you're better off in the other theater at that point, unless you qualify for the owner's discount and are really stingy.
And if you didn't like the viewing, or the service? Fill out these forms in triplicate for (most of) your money back. And the complaints book, that's also in the other theater, because, y'know. Why wouldn't it be.
