This is part of a series of reviews of Doctor Who in chronological timeline order.

Previous Story: Loups-Garoux

This is a weird one, I don't have any strong opinions about it, which makes it hard to write a review. The Russian setting is a fun one and it was utilised quite well. The accents are authentic, but the voices could be a bit grating at times (specifically Lena Korolev). There's some really cool concepts here, most notably the last remnants of humanity sending their minds back into the past to escape the heat death of the universe.

I don't think it was intentional that this planet ends up being the one featured in A Christmas Carol but that's an interesting tidbit regardless. Peter Davison and Mark Strickson are a great combo, they always put their all into every story and it shows. This story isn't anything above average for them, but it shows how high their average is.

I do feel a bit bad for Mark Strickson given how little content he appears in, it took him 5 years after this to feature in another story. All in all, it's not a remarkable story. It doesn't expand anything in particular and doesn't develop this companon dynamic. But would I say I wasted my time with it? No.
