An interesting take on classical mythology, that ends up devolving into Just a bit of a boring runaround.

I really like what we get here of this take on the Greek Gods, giant, immortal scientists with some incredible powers, intending to create the perfect, peaceful race, with Prometheus, wanting to give humanity free will.

I love just the scale of this, the image of the temple, showing just how incredibly vast it is, acting as a complete city, even though it doesn't look like that from a distance. The how the ageless nature of the gods is communicated, Prometheus seeming completely unphased by having to knock against a wall for thousands of years to escape, and where we originally find him, chained to a rock that was once a mountain.

There's also the ambiguity of where these 'gods' fit in, if The Doctor found Prometheus on Earth, if he brought him there at the end, if none of this was connected to Earth at all. It leaves itself open ended, which is definitely appreciated.

Unfortunately, while the setting is well fleshed out, the actual plot of this story itself ends up being very standard Doctor Who fare. Running around some corridors, escaping being killed at the last second thanks to K9 and the sonic, etc etc. I think more interactions with the other gods could have done this story a lot of good, but as it is, well, it's fine.
