The final straw for me was the day after the episode where Beth died aired. It was the morning after that episode aired and I hadn't had time to watch it yet, and I was scrolling through Facebook when a giant "RIP Beth" picture popped up on my main feed from the official Walking Dead account.
The official account couldn't even hold itself back from posting spoilers for 24 hours after the air date and I realized I didn't even care that the episode had been spoiled. I didn't care about the characters, or the plot or the direction the story was going.
