In their main theatres they now have stroller screenings where the volume is reduced and the lights stay on low. They've done the sing-alongs. They also let you rent out the theatre to have xbox gaming with Halo or whatever you want to play.
Sadly the general theatres aren't great at policing the cellphones or no talking. Although I've heard several times that they're interested in the cellphone jamming, but it's illegal to jam 911. I have heard, and noticed, that in a lot of the newer theatres you get really poor reception in the general theatres. It could just be coincidence from them being out of the way and all the steel, but I do appreciate it nonetheless.
