To get through one of the sealed doors, the question is "Who had the most number one singles; Elvis or The Beatles?". The answer is given as Elvis. This is only true for the UK. Worldwide, it is The Beatles. While it's understandable that Martha's mother in the 21st Century would give the answer for the UK, a ship's crew in the 42nd Century would probably have used the answer for the whole globe when creating the question/solution.

As fast and intense as Doctor Who gets
19 May 2007 | by lemmingologySee all my reviews

I'm going to cut to the chase here - this episode left me absolutely breathless. The action and suspense kicks off right at the start and just does not let up until a couple of minutes before the end.

Where do I start? It has twists and turns all over the place. David Tennant and Freema Agyeman are both particularly magnificent in this episode, both of them instantly fitting in to the surroundings they find themselves in, and once again, I hate to admit it, but Agyeman is already outshining Billie Piper in the assistant's role. Tennant is also especially brilliant in the final 10 minutes or so, as the source of this episodes menacing enemy takes its effect on him. Ex-EastEnder Michelle Collins is an inspired choice to play the ships captain Kath McDonnell, as she plays the role of the strong female leader to perfection. There's also a completely unexpected cameo by delightful former Hollyoaks girl Elize du Toit, and a sinister turn from Martha's mother, played ridiculously well by Adjoa Andoh. Let's just say Jackie never hated the Doctor this much...

The biggest doffing of the cap, however, has to go to Chris Chibnall for a truly brilliant script. The plot line and the twists in it are unbelievable, it keeps you guessing all the way through, and the revelation 10 minutes from the end when the Doctor finally realises what's going on left me gasping. As an episode it's slightly reminiscent of The Impossible Planet from the last series, although this episode is ten times faster while still being nearly as scary and unnerving.

All in all, a must-see. This series is turning out to be the best yet - halfway through and there hasn't been a single poor episode yet.
