Yeah, Netflix is streaming only, presumably to stop people from getting it for a month and then downloading everything that even vaguely appeals to them.
Anyway, I would definitely suggest you get the trial offer before you start a subscription, because you do not live in the United States. I live in Canada, and our Netflix selection is staggeringly smaller than what Americans have access to.
I mean, I would be a little stunned if you didn't have Doctor Who, it being a British show, but seriously, vast swathes of Netflix material are trapped behind regional distribution agreements and they don't have the licenses to distribute them outside of the U.S.
