The Doctor, meaning to take Mrs. Clark to the post-War era instead lands during the War in Nazi Germany where for a little boy, a warning poster about an airraid is representative of a monster who has been lurking at night during blackouts.

This short story combines a character piece and a monster story and does a decent job with both. The plot moves and the sound design is well-done. Constance's thoughts on how the British are feared and bombing this town are only lightly explored but Miranda Raison's reading does give this story sufficient emotional weight.

The Counter-Measures crew are out after a nuclear submarine that sunk under mysterious circumstances with all hands aboard. However, to do that, they'll have to ride along with a new agey undersea filmmaker known for his quest for Atlantis. When they arrive, they begin to discover that the boat holds many secrets as the crew is gone without a trace. Of course, as usual, Sir Toby holds many secrets of his own.

Overall, a solid episode. The story manages to capture the required claustrophobia of a ghost submarine story while doing a good job building a sense of mystery. There are a few off scenes, but this is mostly a very solid episode.

Gilmore goes undercover to try and locate a rogue physicist and ends up involved in a new invisibility experiment that tries a psychological approach to invisibility. The problem is that the device undermines the mental stability of the wearer and the head of the gang is an unstable psychopath to begin with.

TThe idea at the core of the story regarding the invisibility machine is actually very clever and the unexpected side effects seem very plausible and produce quite a bit of drama as the wearer's sense of sanity and self are undermined. Add the high concept sci fi to a generally good action adventure and New Counter-Measures starts off on a high note.

The Doctor becomes a submarine captain as the Time War moves undersea. The story succeeds with a lot of great claustrophobic moments, helped by some very solid sound design. There are also some character moments that are subtle but well-done.

What hurts is that the way the Dalek threat is dealt with is pretty anti-climatic. I also think getting another story with a creature who could end the Time War is a repeat of an idea we've visited too many times already.
