Theatre #5 is the basis for this review.
Short summary: The projector has strong barreling with terrible colour accuracy. If only that was the main issue...
The audio in this theatre is nothing short of broken. Storyline dialect was at times un-distinguishable. The bass is heavy, loose, and super sloppy. The front drivers sound muffled by the old display. All spoken word are output by these speakers, which leave you feeling like you need to sit closer to the screen to hear.
The movie I saw was Black Panther. Once home, I watched every trailer available and was shocked how much better my basic home setup sounded.
