We went to see Thor in their new "IMAX" theatre. Make no mistake, this is NOT the IMAX you know and love. The experience was hardly different than a standard digital 3D movie. The projection was sub-par, not crisp/clear as you'd expect. The depth in the 3D was very weak, scenes that should have been in your face seemed more like offset 2D panels due to the short depth of field. Sound is only from 3 central points (2 rear and behind the screen) and didn't provide that feel it in your gut oomf you expect from IMAX. The lack of curved screen also meant the edges blurred if you shifted even slightly.
The seating, while new, was also sub-par. Chairs were smaller than normal for IMAX, less leg room, and the rise was the same as a regular theatre so the person in front of you could obstruct your view if they leaned forward.
In no way did it live up to the IMAX experience you've come to expect.
