Dexter had some great seasons but it grew to have snarkability. Trust me, Breaking Bad is an amazing series for anyone who can handle violence and some low life stuff. I barely could but I did and it was very worth it. This is the only show ever where they had a full on story from start to finish that made sense and no shark jumping anywhere. Direction, writing, cinematography, better than most films.
Better Call Saul is turning out pretty good too, so far.
IMO, Durham County is a much better series.
