I'm downgrading AMC Deer Valley 30 to 3 stars.
On the latest visit (today), my popcorn tasted like cardboard. I don't know if it was super stale or had some other problem, but it was terrible.
We saw a flick in one of their 4 big theaters near the center of the complex. The seats don't lean back at all, which is kindof a bummer. Our movie also had some sound issues today. There were a bunch of incidences of garbled sound and overlapping sound. We'll be opting for the Norterra Harkins (off the I-17 & Happy Valley) from now on.
