Roughly about a year apart I've tried two of the $5 Monday specials, and maybe one or two other movies over the last four years.
Each time has been pretty terrible. The picture quality is horrible. Sound is mediocre.
Went to see the Avengers this week (7/2/12) and the picture was off-center (large black border along the top and right hand side of the screen). Either something was in the way, or they need to actually aim the projector. The sound quality was ok, good at times, but about halfway through the movie during a large action scene, all of the speakers cut out except for the voice/center. This lasted for about 15 minutes, then would come or go through to the end of the movie. Unacceptable. At least you didn't miss any dialog, but you're certainly missing the "experience".
I won't be back even if it's $2 Mondays, unless I hear that things have improved.
