Seconding all of these. (Thirding, in the case of
Doctor Who and
Arrested Development).
Make sure you watch at least the first two series of
Doctor Who before you start
Torchwood. I can't remember if the latter gives away any plot developments for the former but it probably won't make much sense unless you're already familiar with the Whoniverse anyway.
I can't remember what else is on Netflix but I'll go through my list of favourite shows later and look.
