Harkins theater at Superstition Springs is a great stop for a movie.
Matinees are only $8 (as of this writing), and they've got a number of theaters.
The inside of the theaters sound great, and the screen quality is also on point. The seats themselves are a bit dated, but comfortable.
The parking lot outside is pretty large, so finding a space isn't an issue.
Their concession stand offers quite a bit of options as well (not just your usual candy and popcorn) so if you haven't had a bite to eat and you're rushing to the movie, you'll be able to find enough to fill you up.
Some of the theaters here are a bit small, so make sure you show up early to grab a good seat. I've had to sit in the front 2 rows a couple of times and it's a strain on the neck. :)
