'Dina' on iPlayer

Hello

I'm halfway through watching this fly-on-the-wall documentary from the USA, Dina.  It's about a middle-aged autistic couple, preparing for their wedding. It's a bit slow to get started but reveals more of the characters as it goes on, and I thought it might be of interest to anyone on this forum. It was on BBC4 on Sunday night. 

Anyone already seen it and want to discuss?
