A Town Called Mercy

That was very interesting. It's not often Doctor Who attempts to tackle a subject as thorny as war crimes and the competing claims of justice and mercy. A Town called Mercy handled the subject matter pretty much as well as it is possible within a show with Doctor Who's constraints. I found its resolution unsatisfactory and I think it showed fairly precisely where one of Doctor Who's limits lies.

( More rambling under the cut, including some discussion of treating the Holocaust within Doctor Who )

I think A Town called Mercy ultimately failed. But it failed partly because it reached too high and thankfully, given there was a chance to fail really, really tastelessly here, it at least failed with dignity.
