This was a great episode. I think I liked it so much, because I GOT it, I am from America so that was something I learned about a lot when I was little! Though I was a little icked by how they felt things would have turned out if JFK was not murdered.
I loved the idea to have JFK kill himself. Though that brings up a mistake that I noticed. Just the beginning of this episode Lister explains the paradox of being killed but yet not being killed because of the future version of them would never have lived. So how could AU JFK kill himself and not have the same thing happen? I ask myself that question everytime I watch this episode.
Despite that it was a great episode and I love to watch it.
