What did you find to be dumb about the episode?
That's setting the bar pretty low. And for me, there were no redeeming qualities to raise it back up.
More to the point, someone could have found the victim within that hour and stopped the whole thing, but no-one did because they were too preoccupied watching it on TV.
Then there's the framing and lighting on that last shot, which made me sit up straight and go, "oh, crap, I need to start paying closer attention to the film-nerd details in this show!"
