Oh yeah, my favorite thing about Doctor Who's early years is the fantastic character development. It was originally conceived as an ensemble drama, so all the characters really get explored in depth & given their chance to shine. The screaming damsel in distress stereotype didn't exist on the show till much later, and even then it's the exception rather than the rule. I've learned that whatever 'the conventional wisdom' is regarding Classic Who, it's usually entirely wrong! I've rarely been so pleasantly surprised by any TV show as I've been watching Classic Who. :)
