As some people with autism have sensitivity to sound and light, for these shows the volume of the movies is turned down a bit, and some low lights are left on. Afterwards, The Ritzy lays on light refreshments for cinema-goers to meet and chat.
I thought this was pretty cool. Obviously, it won't appeal to everyone on the autism spectrum, but I'm sure that there are some people out there who will love it.
I'm sure other cinemas have these kind of events as well, but since I came across it first at The Ritzy - hats off to them.
