I'm kind of surprised by all the negative reviews but I've been coming to AMC Star for many, many years now - back when it was just Star Cinema, before the iMax. I've been a big fan of the service(not really the prices-but its a movie theater..what else is new?) I've not found the bathrooms dirty nor the carpet trashy - reading these reviews I feel like I'd be walking into an alley or something. I've gone from everything from sold out showings to myself being the only one and enjoyed 99% of them.
Strangely, I read one(not sure if there are others) complaining about the behavior of other patrons...one person mad about middle schoolers being noisy. You need to speak with a manager if you want to address issues like that. They don't have hidden cameras or something in every theater. You can't just feel mad and hope someone magically kicks them out.
