Homeland and Walking Dead, for me.
For as much acclaim as she gets, I find Claire Danes' performance to just be strange and inauthentic. The rest of the show is pretty great.
Andrew Lincoln tries so hard to be tough and complicated that the actor that plays his son even upstages him with a more subtle and subdued performance. And that kid just stands there silently in most episodes! Again, love the rest of this show, too.
