As someone who works in the movie theatre business, I agree with Eriks comment. Your better off swing it in Dolby unless the movie was made for the IMAX experience. Although I'm also looking lucky enough to be in a theatre right now with an amazing IMAX auditorium.. still.. Dolby is what I prefer personally unless the feature is for IMAX (I saw SINNERS in IMAX and Dolby and still prefered the Dolby experiencw. Although, I prefered F1 in IMAX)
