And finally, we have the TV performance that caused more social media distress than any other over the past twelve months. Ed Sheeran appeared in the first episode of Game of Thrones' seventh season as a Lannister guard whose singing catches the ear of Arya Stark.
Arya then joins Sheeran and his pals for some food and drink, in a scene that drags on for almost five minutes, with Sheeran plainly visible throughout.
Though Game of Thrones has featured famous faces in cameo form in the past, they've typically only appeared on screen for scant seconds, whereas Sheeran's appearance was incredibly distracting for the scene's entirety. It's not so much that he gives a bad line reading, but that he seems so out of place, and shouldn't even have a performance to give in the first place.
It's the epitome of self-indulgence on the part of both Sheeran and the show, with the resulting backlash causing the singer to quit Twitter shortly thereafter. Hopefully HBO will learn their lesson and keep the celebrity cameos subtle from now on.
