What's interesting about the opening to Attack on Titan is that it gets you so stoked and hyped for the show but then once you actually get to the episode it's all doom and gloom for the characters, quite the reversal of emotions. And yet, you can't get enough of it.
Reaching outside the box on this one but after watching the intro to The Newsroom on youtube, I binge watched both seasons that were out at the time. Oh sweet, sweet Jeff Daniels.
Or perhaps the opening to Attack on Titan.
