I'd broadly agree with this. It's a story that easier to admire, at least a bit, than to love. In many ways it was undermined by the previous year's Silurian two-parter exploring similar territory less successfully. I'm glad they didn't go for the easy option of killing all the gangers, though. And I share NLSS child's upset at Amy's ganger's death. I do think the idea of substituting a companion for several stories is a bold and mostly successful one, although the fall-out from the situation in the second half of the season is handled badly.

Big Dumb Two-Parters may be making a comeback sooner than you think...
