On season 2 of Mad Men and feel disinterested

I started the show with high hopes, since it often comes up in the list of best TV shows ever. But I am halfway through season 2 and feel bored already.

When the show does the advertising bits, it's really great. But I feel like more than half of the show is only about the personal drama of characters - not the good kind but the juvenile, teenage love slop kind. It doesn't help that almost all of the characters have been very unlikeable so far. Even Don Draper with his casual infidelity and every female character only existing as a love interest.

Does it get better? Convince me to continue the show.
