The Doctor arrives on Titan, a moon around Saturn, the last remants of a human settlement are still there, and they’re trying to explore the depths of the sea.

The pre title sequence seems a bit pointless, I think Stephen Moffat said that what used to be episode one of a classic era story is now the pre titles bit. Other than a little bit of scene setting, the Doctor turns up says Hello and that’s it!

I don’t read a lot about stories before I listen, so while it was a nice surprise for me, you may already know, that this features the Sea Devils. I’ve been watching the Silurians over the last week, and also just heard the first of the Paternoster audios. So I’ve been a a bit a theme lately - all by accident. It is just as well that I did as this story references the events of (and) The Silurians.

There is a bit of rehashing of what’s gone before, the two species afraid of each other, a bit of double crossing, the virus etc. The Sea Devils voices not the best on audio, they weren’t the best on TV either for that matter, so you do need to concentrate when they’re talking.

This is the kind of story I enjoy; a bit reminiscent of the impossible Planet/Satin Pit, the last people on a remote outpost, trying to stay alive in harsh conditions.

Its not the most complex story, it doesn’t go into much detail and the themes have been done elsewhere. It might be a nice set up for a story that could come later, but as it is it's Ok, enjoyable. A really good idea or another component would have elevated this to being something special.
