A lot of people didn’t like season 1 of the Expanse (I enjoyed it) and said it got much better after that. I will say the Amazon seasons aren’t too great either as it looked and felt more like a low-budget soap opera.
Better Call Saul and Breaking Bad were both made by Vince Gilligan who worked on X-Files as well so they’re a good choice assuming you’re one of the few who haven’t already seen them.
