We absolutely LOVE the Rave Theaters. They are always so nice and clean, and we have rarely encountered a problem there.
Once, however, we were in the theater, and the movie kept skipping, and they would have to pause it, and get it back on track. This probably happened only 4 times throughout the course of the movie.
At the end of the movie, they had attendants waiting outside the theater giving each of us a free ticket to come back for the movie of our choice. It was not necessary, but they did it to keep their customer happy.
We do enjoy the Rave.
