I'm glad you enjoyed Inferno in the end. Interesting story. I guess we are (or at least I am) jaded with alt universe stuff these days since it's such a common sci-fi trope. Inferno was jolly good though.

I know quite what you mean about random chases in the Pertwee era. I've said this to you before I'm sure but I swear at times the script says nothing other than "they run about in the woods a bit -- 5 mins".
