well, watching them now is kinda difficult because they are now somewhat lower quality. that, and that constant machine noise, buzzing and beeping throughout the entire BBC showings on PBS TV was terrible. I watched them between 1985 and 1990. my dad was religious about recording every episode that aired, so we also watched a lot of reruns.
anyway, while the sixth dr was active, we mostly watched tapes of the fourth and fifth dr - it's the fifth dr in that image I quoted, and the very few episodes he had of the previous ones. we didn't watch much of the sixth, but i saw a few of the seventh and i was like ...nah, this isn't for me.
