For a story that sprouts as much conversation as this one, it's terribly inconsistent. I just can't decide how I feel about it.

There are plenty of cool and interesting concepts here. The dream sequence is very cool, I like it when Doctor Who gets experimental. The idea of the locals being very scientifically advanced despite appearances is interesting, but wasn't explored or expanded upon at all. I like the design of the Mara, both in the dreamscape and in reality.

The guest cast is interesting, too. They all have different things going for them. Unfortunately, it's overshadowed by the complete lack of substance from our regular companions. Adric somehow managed to be even worse than in the previous serial, and I'm getting really tired of him fake-siding with the bad guys to save his own skin. Tegan continues to get on my nerves - so far, her only character trait is complaining about wanting to get to work on time. And Nyssa continues being sidelined - she isn't even in this story at all!

At least the Doctor is finally coming into his own. Five is beginning to grow on me.
