My first movie in PVR IMAX was Interstellar, honestly while watching the movie I had a feel that my seats were vibrating like they said in the IMAX 3D countdown EARTH SHATTERING sound. it gave me impression that I should prefer to watch the movies in IMAX which is being released in that format.
BUt most recently FURIOUS 7, MAD MAX and JURASSIC WORLD doesnt give me any chills in the sound experience. It forcefully made me to think they are cheating the visitors in the name of IMAX. I had a feel like watching the normal 3D movie in IMAX screen.
Not sure it will be same in other IMAX screens.
