Funnily enough most of the shows that I had a hard time getting into I stuck it through and ended up loving them enough to rewatch them. Game of Thrones (took like three seasons to hook me), Breaking Bad (about two full seasons), Mad Men (three seasons), and took me two full watch throughs before I loved the Sopranos. Only reason I kept going was because I was binging with my girl and she kept urging me to keep going.
The ones that never did shyt for me were:
True Detective
House of Cards
Ozark
Six Feet Under
Boardwalk Empire
Louie
Modern Family
