I think Doctor Who can be a bit predictable sometimes, when in every historical episode some mythical creature turns out to be an alien that wants to destroy/conquer the world. I think it's refreshing when they change the pattern a bit, but I see your point. The episode set up the expectation of a terrifying ghost enemy, and it did not deliver. I think you've gotten to the core of why the episode seems to have been so poorly received by a lot of people.
