I want to open this thread by saying: Thanks doctor who, I didn't want to sleep tonight anyway.
The villains are actually terrifying, and the fact their motive is relatively unknown makes them even more so. Add in the clifhanger and you've got a solid episode. The characters are actually all quite well rounded from the cowardly scientist to the rather obvious couple of signer/deaf commander (unless they do a bait and switch and she's actually more bothered about another crew member.)
The setting is great and adds tension without being too over the top as well as having safety features that make sense for a change.
Also, sonic glasses are still awesome.
