We close out our Peter Capaldi retrospective by talking about the most Peter Capaldi episode to ever Peter Capaldi: The one-hander "Heaven Sent." Well, it's technically a two- or three-hander, but who's keeping count? We break down just what about his performance helps make this episode work as beautifully as it does, while also examining how Steven Moffat's script and Rachel Talalay's direction put their star in the best possible position to succeed. We also get into some more general thoughts about where this episode and the 12th Doctor's era as a whole fit in the larger story of the new series. Then join us next week as we do something new, or possibly classic, as we look at two efforts to revive Doctor Who, one failed and one successful: The 1996 TV movie with Paul McGann and the 9th's Doctor's debut adventure "Rose"!
