Me and my fam go to them pretty often. At least once a year. Saw stageplays of to kill a mockingbird, the book of mormon, little shop of horrors, and loads more.
I saw this one dope ass theater production that they called a "live comicbook" cant remember the name as it was like 5 years ago, but they had a lady in the center of the stage that was surrounded by different things and she played sound effects, then they had 3 voice actors who voiced lines, then on the screen they showed comicbook panels for the story and the voice actors did lines as the comic progressed. Was really dope.
Also saw the blue man group. Wasnt the Vegas show, but still pretty dope.
