Hey, guys...do 당신 have to watch the 1960's series to understand the 2005 ones?

No not really, it helps if 당신 want to understand 더 많이 but 당신 dont HAVE to watch the 60s Versions. But make sure 당신 dont start watching a series really far on because then 당신 will be Very confused.

It's not a must but it helps some. Having said that, There's some good episodes from the classic series I think you'd enjoy, particularly from the Tom Baker era. Check it out.

I don't really think 당신 have to. I started watching some old episodes a few weeks back and to be honest I didn't enjoy it all that much.
당신 don't actually need it to see them to understand what's going on and the doctor don't really dwell on his past. So 당신 might miss a few nod here and there but nothing major.

Nup. i started in 2005 when eccleston was the doctor

Dude, 당신 don't even have to watch the 1960s episodes to understand the 1970s episodes. 당신 can pretty much jump in anywhere.

Start from the beginning of the 2005 series - it's been designed so 당신 can do that. There is no way 당신 could go back and watch all of the classic Doctor Who - if 당신 watched 3 Doctor Who episodes every single day, it would take 당신 over 2 years to watch them all!
