I always go to Harkins to watch movies. This theater is the closest to where I live. The theater is good and I watch movies here if it's during the day. I do not go here at night, because it becomes a teenager hangout and teens are loud, have no manners, and text all through the movie.
I wrote about this to Harkins customer service. I told them about a theater I use to go to called the Alamo draft house in Austin, TX. Where if you were loud or texting during the movie they would throw you out. I never got a reply, so I assume there is no policy against it.
Overall it's a good place for a movie, good service, nice seats, nice screen, just don't go at night.
