Personally, I think the golden age of Dr Who was the 70s. That decade started with the debut of Jon Pertwee as the Doctor, followed in 1974 by Tom Baker (the scarf guy). Calling the special effects bad or dated or whatever is missing the point entirely, the show was never about that. The thing that made the show a cult classic was the quirky writing and performances. I've seen some of the new Who and I liked that too but for my money I'll take the 70s version over that anyday. I wouldn't start off with the first 2 doctors (the ones in B&W). Not that they're not good, but the 70s was the creative apex for the series, at least in my humble opinion.
Cheers mate!
