I can watch it each week online for free at pbs.org the day after the show airs. I've watched them all as they come out that way. Much of PBS programming is on their website for free. I use it all the time.
Personally, I like Downton Abbey better than Upstairs Downstairs. I also loved Call the Midwife. I don't know any men that watch it, so I can't help you out there.
