i want to start watching doctor who, but i know there is a lot of episode, do i have to start from the very beggining? what is the best episode to start from?

I would definitely start with 'Rose' season one of the new series, they'll catch 你 up on what 你 need to know. And if 你 like it well enough 你 can go from there! Hope it helps!

The best one to start off with is "Rose", like the people above me said(even though I started with "The Impossible Astronaut").
If 你 really want to go back and start at the very beginning, "The Unearthly Child" is the first episode. I think it's still on YouTube, and if not, it's on DVD somewhere in te vast expanse of 太空 and time.
But for the modern Doctors, start with "Rose". :)

I would strongly advise 你 to start watching from the beginning if 你 want to know the whole story. Start from the new Doctor Who series. The best episode to watch first is "Rose", the start of the 9th Doctor

I know theres lots of episodes, but you'll be fine if 你 start with the modern ones:) So I'd start at Series 1 (2005) and continue there, that's what I did. 你 won't be 迷失 或者 anything.

If 你 were to dive strait into doctor who either series 6 或者 the new on that's coming out fall 2012, than 你 will most likely be very confused and put off the series. so 你 should start with the the new doctor who ie. from 2005 with Christopher Eccleston "Rose". 你 wont be 迷失 and you'll get a lot 更多 of the humor.

I would start watching from the beginning of the new Doctor Who era like everyone else says. Then if 你 like those episodes and want to watch other episodes from the classics 你 could watch a few on Netflix 或者 on Youtube.

Start from the beggining of the new series. If 你 don't it won't make much sense.

I started watching doctor who from the beginning of the ninth doctor and i have been watching it ever since.
