I am a lover of Sundance Theater. It was hard for me to consider trying the Marcus Theater in Sun Prairie. I "got over myself" when Star Wars came out and boy was I impressed. Sitting in a big comfy lounger, cuddled up with my guy felt wonderful. The screen and sound quality was excellent. The food prices are not bad and you can get a drink from the bar.
I still prefer the independent films at Sundance but for your blockbuster the Sun Prairie Marcus fills the bill.
