I can’t remember if I re-watched the Tenth Doctor’s mini-sodes; I kind of think I did though, because they are fun.
Having finished S5, I just re-watched the two-part Red Nose Day special, ‘Space’ and ‘Time.’ They’re just a bit of silliness designed to raise money for charity. Karen Gillan is particularly delightful. But they’re no ‘Time Crash.’ I find the sexual stuff annoying, and the recursiveness is just a bit too eye-rolly for me. (Not that ‘Time Crash’ wasn’t recursive, but it made up for it in charm.)
Fun, but not Moffat’s best work.
