What's one show you thought you'd hate but ended up loving?

We all have those shows we dismiss at first glance. Maybe the premise sounded sort of silly, or the genre wasn’t really our thing, or maybe too much hype made us completely avoid it. Every now and then, though, one show unexpectedly changes our minds. For me, it was The Americans, New Girl, and Nathan for You—shows I wouldn’t normally go for but ended up loving. So what’s a series you reluctantly binged?
