This is no doubt the most boring and prudish opinion in the universe, but I would have enjoyed Halt and Catch Fire if it had more computers and less sex.
So I initially gave up on this show part way through the first season, but not because I hated it exactly it just fell off my radar and didn't grab me. The sex in it did seem...out of place and kind of shoehorned in. And the Joe MacMillon character's out of control Jobish behavior irritated me. But the season 1 finale was solid, I liked many of the characters and the subject matter so I went back to it and I'm so glad I did.
It is now one of my favorite shows of all time. The characters were slightly retooled after season 1 and their bizarre family structure is very compelling. The backdrop of the era was why I really showed up for the show but the characters and performances were why I loved it.
