Maybe their target was a female audience, but I know several guys who watch it and seem to enjoy it and no, for the benefit of the user who posted above this one, they aren't gay or effeminate in other ways.
Call The Midwife is amazing. I watched every single episode so far and I love it. You don't get TV Shows like this one anymore and I think that even though Downton Abbey is quit good, Call The Midwife beats it handsdown. My mum and I watch it, but my dad and brothers have watched it once or twice. Guess its just who this show appeals too as me and my mum have read the books as well
