As you'll see (and as you'll probably expect if you've read any of my other blog entries), my top Hartnells don't necessarily include the most acclaimed or seminal serials. Certainly one celebrated story is conspicuously absent: "The Aztecs." I simply don't feel the enthusiasm for it that I feel for the others on my list, and for me, it's more worthy for what it represents (the first surviving historical) than for what it actually achieves. But as I noted when I began counting down my favorite Hartnells, there are very few First Doctor serials I actively loathe; even the ones of which I'm not especially fond have premises I respect (e.g., "The Space Museum") or individual episodes I enjoy ("The Keys of Marinus," "The Daleks"). In fact, I think the only Hartnell I can't stand, top to bottom, is "The Reign of Terror." But most of the Hartnell era I consider a joy: sometimes just for the aspiration, but often for the execution as well.
