I'm not really sure what to make of this one. Generally speaking, I hate the "dartboard" critique BF often receive, but this release did stick out to me as one of the oddest crossovers in the Whoniverse. That said, I'm always one to give it a go and see if I love it. I can't help but feel this was a wasted story, and the mind wipe was just predictable.

Despite the long runtime, the episode does quite a good job with the pacing so it doesn't drag in any one given segment. The story itself just lacks a certain punch for me, which I think had it that punch it would've landed better. I needed more of a reason to be invested in this story, and crossover, than what we actually got. The fairies are rather reminiscent of the Moffat era as creatures and it does stick within that theme, but ultimately its a very safe story that doesn't push the boat out or cover new ground.
