Peter Davison's first story as the Doctor. It has the 5th Doctor experience more post-regeneration issues, than the previous ones, which highlights the seriousness of regeneration (and why you shouldn't just do it for fun... Romana). Also gave them good moments to have callbacks to past companions and incarnations of the Doctor.

Didn't love the fact that they had Ainley play the Portreeve. Despite the make-up, it became obvious (especially in close-ups) that he was the Master in disguise.

Not the event filled story. It's mainly there to introduce the audience to the new Doctor. A big deal, as (because of his long tenure) a lot of viewers had probably only known Tom Baker as the Doctor. Suddenly, this new guy shows up and is the new Doctor.
