I loved Mad Men but I felt it wallowed in the sexism a bit too much. Yes, it was there, it was bad, but a little of it goes a long way. The showrunner sometimes neglected the main characters for whatever new character was tickling his fancy (Bob Benson, Megan).I'm not going to go into spoilers then in case you do watch it, but I'll tell you what I like about the show in general:
1. The mysteriousness and mystique of Don Draper.
2. The illusion of how "great" things were in the mid-20th Century versus the reality.
3. Showing women's perspective on the sexism of the time.
4. The thought process that goes into creating ads.
5. All of the characters and their personalities.
6. The show covers from 1960 to 1970 and you get to see how everyday characters are affected by the changes in society. You get perspectives from people who wouldn't have been on the frontlines of the Vietnam War or the Civil Rights Movement.
7. The production design is first-rate. It's so well done, you actually believe you're looking at the 1960s.
8. Character arcs continue from season to season, not just with Don Draper, but with all the characters.
9. Trying to figure out the double-meaning behind the themes of each season.
10. The insight into corporate culture and office politics.
11. The clash between the generations that becomes more prominent over time.
12. The slower and deliberate pace means that nothing is rushed.
13. The exploration of the different romantic relationships. Especially comparing the ones that work versus the ones that don't and their ups and downs.
The show feels pretty authentic except—as is often the case with historical recreations—the dialog occasionally betrays the illusion. Language was still a little more formal back then and there are turns of phrase and lingo that were different then than now (i.e. "leverage" or "I need you to").
