Andy_Panthro: Firstly, classification of silurians as Homo reptilia, which is a bit silly.
I just figured it was a joke. But it was silly nevertheless.
Andy_Panthro: The total number of silurians seemed very small compared to the UK armed forces they'd have to defeat if they wanted to take back the planet (let alone all the other countries that might not be keen on the idea). I'd have brought that up in the negotiations.
Well, if they were negotiating with the soldier lady, that would have been relevant. She seemed to underestimate the level of human development, but the guy they were talking didn't, and was buddies with the scientist, who surely must have informed him about the current state of affairs on the surface.
Andy_Panthro: How can the doctor put his arm in the crack? In the earlier episode with the angels, the Dr tells people not to even look at it when it's open like that...
Special time lord resistance? Part with the crack was very sad though :(
Well, that said, from what I've seen so far (the first new season and the current season), Doctor Who's strength isn't the watertight plot XD
