Saw an IMAX movie here the other day. I like the fact that you can reserve your seat in the IMAX theater (maybe all IMAX theaters are that way, I don't know). The actual movie-watching experience was great. The seats were comfortable and lean back (although they don't fully recline). The concession stand was understaffed so I had to wait awhile to get my snacks. Typical food at typical movie theater prices. Popcorn was very good, and they do have a Coke FreeStyle machine. They put a sign on the FreeStyle machine that says free refills are for large sizes only, which I've never noticed at the Concord Mills AMC. And I'm pretty sure nobody follows the rules here because that's ridiculous!
I purchased my ticket online ahead of time. There's a kiosk outside that you're supposed to be able to type in your confirmation number to get your ticket without waiting in line. The machine (multiple ones, actually) couldn't find my order so I ended up having to go inside and have them scan my credit card to find my ticket. Very annoying. I don't know if that's not normal but I won't be trying that again, at least at this location.
