Original doctor Who and new doctor who are pretty much different shows. The early ones aren't bad, but they're nothing like the new ones. As is the case with most things from it's time, the original doctor who was conversation...lots and lots of conversation. It treated it's audience as though they had an attention span and intellegence. The dialogue is clever and witty but you need to have the knowledge to understand why it's clever. New doctor who actually throws away a lot of the old doctors rules, makes up new ones and has a whole different pace going. It's very with the times and the focus is more on action and simple humour. Both are very good, but they're not really comparable to each other, and there's no way that you can watch the whole thing anyway. A lot of it no longer exists. You see, back inthe 60's and 70's the BBC (and many other stations) were under the impression that no one would want to watch the shows again, so to save money and space they taped over a lot of their shows. In the 80's they stopped and in the ninerties when they first tried to revive it (Eye of harmony wtf?) they kinda figured that they'd need these shows back. If only so they kept with the plot. When they finally rebooted the show they had started collecting the old series back, buying it from other countries, peoples carboots. Heck we have one episode where they could find the sound but there's no video footage so they just used stills
Which is actually quite ingenious.
But the bottom line is, old doctor who....probably wouldn't appeal to anyone who watched new doctor who first. I watched tom baker, grew up on him, and I'm an avid fan of old sci-fi annyway. So if you do go back and look for them, do so with your eyes open because they will send most people to sleep, especially when you realize that most original Dr Who plots are multi parters. I don't think Tom Baker has any plots that are less than 4 parts, and there's virtually no action in the entire thing. Brilliant show though and well worth a watch if you can get your hands on it and you are a fan of old sci-fi. But not something for everyone. New doctor who doesn't even pick up where old doctor who left off anyway. I mean in the last thing they put out (a film) The doctor was taking the master from skaro to Galifrey after he had been executed on his 13th cycle so he could never again regenerate...so he possessed a body, tried to steal the doctors and fell into the eye of harmony where he was destroyed. First episode of new doctor who and there is no Galifrey, and no Skaro, and no time lords. Fast forward a bit and the master is once again back.If you watched the whole thing as one show it just wouldn't make any sense. *Is such a Dr Who Geek*
welcome to the forum
I'm not a Who fan, but my BFF is. I might be buying one of those Who patterns from you very soon to stitch up for her. I've just added your shop to my favorites. I'm working on opening up my own shop, too. 
Maybe some day I will get around to it...
