We saw Avatar first in the standard 'Real 3-D' and loved the experience so much that I decided to treat my husband to the 'iMax 3-D Experience.' The iMax tickets were $4 more a pop, and the line to get in was ridiculous - and in both our opinions the iMax 3-D version was not any more breathtaking or impressive than the standard 'Real 3-D' version. Save your money and your time and just see the plain old 3-D - but DEFINITELY SEE IT!
