I liked Davison's Doctor a lot at the time, but now I feel strangely reluctant to go back and rewatch his stuff--unlike, say, Tom Baker where it seems to belong to a more distant and nostalgic era entirely. Not quite sure why. I've seen Earthshock and Caves of Androzani in the last few years and enjoyed them.

You're right about the Merka, and I did like Snakedance/Kinda.

Part of me just doesn't want to own a box set combining two Pertwee stories and a Davison because, anally retentive as I am, I'll only want to break it up to put them in chronological order with my other DVDs. :-)
