Location, location, location. Mill Avenue's Harkins Centerpoint has one of the best locations in Arizona. The theatre is located on Mill Avenue, a popular college street, which is a hop, skip and a jump away from campus. And I'm a fan because it's pretty close to where I live.
If you're looking for luxury, try the new Harkins at Tempe Marketplace. But if you enjoy quiet, peaceful theatres, you'll like it here even with the old seats and lack of grub. Even though it's close to campus, the theatre is rarely crowded, which makes it nice when you're running late and don't want to battle the crowds. It's also a nice theatre to go catch a flick by yourself.
