I felt the same way. I can't really explain just how much better season 3 is, but you'll just have to trust me.
The cartel are more involved in the latest series so it ups the stakes dramatically and it just makes for a much more interesting storyline and potential consequences. They also introduce a new character that changes the Byrd family dynamic and it works really well.
I guarantee you'll like at least 2 people in season 3 and want them to live
As for Better Call Saul... It actually gets better with each season, somehow. I'd say it's
as good as BB.
