Most of the time when I want to see a movie, I will go to Airport Cinemas. It is only ten minutes from my house, which is nice, but it also has short lines. Mind you, I don't go on a Friday when the movie has just opened. The last couple of times I've gone to the movies, I've literally walked up, bought my ticket, and sat in the theater within 5 minutes. It's nice to be able to enjoy the theater without the lines.
The theater is clean, with the exception of right after the opening of a major movie, but that is the fault of the movie-goers, not the theater workers.
