I am watching Mad Men. My SO is watching Breaking Bad.
We started Breaking Bad together, and I was grossed out and terrified (I HATE suspense and killing). But I am about the only person on earth who was put off by Breaking Bad. From what I hear, it only gets better as you go on.
I really enjoy Mad Men as a whole. I think the character development and storyline is interesting. I'm never DYING to catch up on episodes, but I've also never been dying to catch up on any show at all in my life. So take that as you will.
MM moves a bit slower and it's more about the characters than it is about "action"
