5. 'Better Call Saul'
The concept of building a show around Walter White's law-bending lawyer Saul Goodman started out as a joke, but eventually showrunner Vince Gilligan realized it wasn't such a bad idea. And with Breaking Bad gone and Mad Men on its way out, AMC was more than willing to greenlight a series with a built-in audience. That's enough to get big ratings for an episode or two, but as Matt LeBlanc knows all too well, people soon stop watching if a show offers nothing but fond memories. Thankfully, Better Call Saul explains Goodman's complex history and exactly how he wound up practicing law in a strip mall. Hopefully they can maintain this momentum for years to come.
