This was a great episode for Series 11, also it was nice to see the "mistaken intentions" trope again, that doesn't happen much in DW.

However, this episode it very similar to Rosa. I think both were good episodes, but if you were like me and skipped the two episodes in-between, it's a very emotionally wrecking run of stories. I'd probably recommend sticking  something a bit lighter in between, such as Kerblam! 

Some great cinematography, too. I am continually impressed by the fidelity and "weight" of shots an effects, and IMHO, are better than the effects in Season 1/Series 14
