- Don was more randy/cocky (less cool/mysterious)
- Joan was curvier (how is that even possible?!)
- Peggy was kind of a slut (tried to hit on Don her first day! Also slept with Pete!)
- Paul was unbearded and not yet a subversive
- Salvatore was unbearded and far more flamboyant (aka single for almost the first season, then blammo, married!)
- Betty sleeps on the wrong side of the bed.
- The music was so cheesy (stand up bass lines and lots of jazzy symbols)
Thank goodness for character development. I can't wait to see what happens next!
ps. I hate it when Don has those Grapes of Wrath childhood flashbacks. I hope they leave those out this season. Ugh!
