As far as movie theaters go, this isn't too bad. As others have stated, the Movie Watcher Card is a must. I think it averages out to a free movie and small popcorn with every 15 and on the other visits, free red ropes every 5 visits, and $1.50 off popcorn or drink on the rest. This could be the because I have a bajillion points (resulting from a post divorce inability to sleep anywhere but movie theaters period).
Parking used to be an issue, but as the Arizona Center's popularity has declined over the years, not so much. The other plus for parking is that it is covered, which in the summer rates a huge WOOHOO. One suggestion on validating would be to remember to do it when you are entering the theater. The little machines that used to be located near the rear concession disappeared when they switched systems, so unless you want to hike back to the front, save yourself some steps.
Best feature: wait a couple of weeks after the movie opens and you will be like the only one in the room; creating your own private screening. Never been huge on PDAs but it is nice to know that you could act like a teenager if you wanted to and it's super cool to see a movie without ten thousand screaming children on occasion.
Worst feature: the football field length hike to your screen. Maybe it's because I do wait a couple of weeks to avoid the crowds, but I always seem to be stuck back in either screen 23 or 24. This also makes popcorn or drink refills a little inconvenient... go in the middle of the flick and you could miss the center third of the movie.
