I didn't vote because not all IMAX theaters are created equal!!!! The technical "IMAX" experience means it's recorded specially, there's special sound, etc. However, it's not worth it to me AT ALL to get all that without the HUMONGOUS screen that's standard with many, (BUT NOT ALL IMAXes.)
So, scout out the IMAX first. If it's a giant screen, GO FOR IT. If it's not, skip it.
(I drove half an hour to see The Hunger Games in IMAX in a small theater with a small screen.... sooooooooooooooooo not worth it.)
