I've been to the Riverview a few times, and I have to say it is the worst theatre that I know of in Philly. Nothing wrong with the building or the screens, but the patrons have absolutely no concept of how to behave. People talking, yelling and screaming at the screen through the show, reading the subtitles out loud to their friends, talking on cell phones, as well as screaming kids and people snoring. My friend actually got physically threatened for asking someone to please be quiet during the movie. The only time it wasn't awful was during a special sneak preview matinée at 10 in the morning. There's no point going here, you're not going to be able to hear the movie anyways and you'll be completely frustrated and angry at the other movie-goers by the end.
