In the classic Doctor Who serial, “The City of Death,” the Doctor and his companion experience bizarre fluctuations in time. They suspect someone is trying to steal the Mona Lisa through time travel, but when they discover six identical versions of the original painting, things only get…well, weirder. Intrigued? Then it’s time for Mark to watch Doctor Who.

Before I delve into any specifics, I wanted to say how great it was that I was essentially plopped down into the 17th season of this show, with little-to-no knowledge of this incarnation of the characters, and it was still unmistakably Doctor Who. I realize that perhaps a Douglas Adams-helmed episode is probably going to be a bit funnier than most other episodes of the time, but I loved how much the Doctor’s sense of humor is still present over 31 years ago. Jesus, this episode aired 31 YEARS AGO.

I like lists. You all know that. This was a long serial–four episodes, each 25 minutes each–so I’m going to treat it like I do movie reviews. HELLO, BULLETED LIST. YOU ARE MY ORGANIZATIONAL FRIEND.
