Perhaps I am in the minority here, but I *loathed* this episode. The story of the Eternals was gorgeous and the historical setting was beautiful, but that's where it stops for me. Nothing else about this one worked for me. I hated the pacing, and the way that the characters bumble along without much happening. The Eternals were pointless and not nearly as menacing as they should have been, and I spent the entire episode waiting for the punch that I felt sure must have been coming. And then it didn't.

Instead of this, what you want to watch is *Sarah Jane Adventures: The Nightmare Man*. That's this concept done properly.
