An awful lot of odd plot points (who the hell points at a sign like that), weird lines (why are we stressing this person is her """real""" mother over Carla, biological family isn't everything), and emotional beats that didn't quite hit (why is Kate a poet now, and also clearly she wasn't going to stay dead as soon as the sand started taking out everyone), which nevertheless didn't stop me from having a pretty fun time. The parts with the Memory TARDIS and also   Mrs Flood at the end were for sure the best

I just wish we'd had more time. I think things would have worked out better if we had more than only 8 episodes
