Are we stupid?

I’ve been watching a lot of documentaries recently, in particular Megastractures on National Geographic. They seem to recap everything, time after time. When coming back from a commercial break there’s a good minute of recapping of what happened in the program so far. We were watching the program before you know, that means we were watching and listening. Megastractures seems to be particularly bad, they do this even during sections of the program.
