An independent theater here in Madison, Wis., advertised a RoboCop
double feature not too long ago, but after I talked to the owners and found they were only projecting a 720x480 DVD onto a big screen, I said "Thanks, but no thanks."
I went to see the Big Lebowski at the theater downtown, probably the same one you're referring to as they're showing Ghostbusters on Halloween, and the experience was dreadful. I don't expect high quality for a movie I know frontwards and back, but people were loud, the sound was bad, the image was slightly smushed, seats uncomfortable, and the drinks were ridiculously overpriced for Madison. I left halfway through. You made the right choice by not going.
