I've thought about starting this show. I've heard great things about it. What's the show about and what makes it so "great"? I really got into "Madmen". I could watch that entire show again like it was the first time I liked it so much.
It really is - by far - the best TV show I've ever seen. As Bamaro said, watch the first few episodes - you'll be hooked. And the best prt is every episode is better than the last. The fourth and fifth seasons are insane!
