It's quite pathetic, and Russell himself admitted it. I can't blame him, because all the circumstances were against him.

The doctor quickly figures out that the fake Stacey is actually a fake. It looks very hasty, given that there are only 12 panels in the entire code, but it's not surprising. It turns out that the sinister shapers want to get home. When the Doctor asks them why they didn't just ask for a lift, they openly aggress him and say that they're going to take over the Earth one day anyway. To which the Doctor gives a standard speech about not even thinking about it, because I'm defending this planet.

In general, it's very clear that these two parts were written very hastily and the sequel was planned to be completely different. The ending is just for show and it's very sad that it happened.
