First of all, I like the 8th Doctor, and I love Doctor Who stories that go for a horror theme.
The reviewer who calls this 'The Seeds Of Doom, Mk II', is right - writer Jonathan Morris has produced a decent story, but he's re-used several plot themes from the Doctor's first encounter with the deadly Krynoid. The halfway cliffhanger on this CD has the Doctor's companion threatened with being stung by a Krynoid pod, you have the human villain teaming up with the Krynoid to save his own skin, and it ends with an explosion, etc. It is like a condensed version of The Seeds Of Doom - and Mr Morris would have done better to have come up with some more innovative plot devices, to keep us listeners guessing. Perhaps he could have, if Big Finish had given the story more air time?
However, the earth of the near-future in this story provides some food for thought, the performances are good all round, there's a good (speeded-up) transformation of a character who tries to hold onto their humanity, and Sheridan Smith as the gutsy, quirky Lucy Miller continues to prove that she's one of the best companions of the Doctor - ever! (example: when getting a security door to open for her, after creating her own pass card, instead of saying "Open sesame" she says "Open sesame seed bun!" :)
All in all, not bad! And I liked Nicholas Briggs' re-mixing of the Doctor Who theme. Is there no end to this guy's talents? :)
