On Delta IV, in the United Federation of Planets, Stardate 45635.2, there is an invasion - but this time, it's not just the Borg. But this time, a mysterious blue box has also appeared on the Enterprise - but has the Doctor been here before?
This is great stuff - the Star Trek universe has been captured perfectly, and the narrative and voices of the characters is spot on. The Doctor, with Amy and Rory are pretty good, and it seems right that they seem just a little out of step with the Star Trek universe they find themselves in. The storyline is great - with a backstory which features an earlier Doctor, and a cliffhanger which paves the way to the next instalment of the story.
Really, what more could anyone want? Star Trek, the Borg, Cybermen AND the Doctor! Definitely recommended.
