This was 100% my favourite classic story so far. For starters, it was nice to have an off world story for the first time in a while, but I also liked the political aspects of it - I really liked the incorporation of the delegates from the different worlds, the drama around Hepesh misleading Peladon and the way the Doctor and Jo incorporated themselves into the situation (also nice how Jo's rather regal outfit was explained in episode one). Overall, a very fun story which I thoroughly enjoyed, and I'm now looking forward to the sequel in the next season.
