All of the theorizing and guesswork about the future of Game of Thrones may give you an endless stream of podcasts to listen to in the shower or whatever, but it's basically ruining the show for everyone.
The Washington Post penned an article Friday calling fan theories "the new spoilers" and saying that all the guessing kills the magic and surprise—especially when those guesses turn out to be true.
Take all that Jon Snow hubbub. Snow's big revival was met with less than shock from viewers, since just about everyone had already decided it was coming and had speculated every possible scenario for his resurrection. Even the story of Hodor—the most Pokemon-y member of the GoT universe—was predicted by at least one person, the Post points out.
On the other side, the endless barrage of fan theories can get people pretty pissed off when what happens turns out to be way shittier than what they guessed. Basically every theory about LOST was better than what actually turned out to have happened.
Basically, the Post's point is that all the theorizing sets up expectations that are either going to spoil you or piss you off when the writers come up with a dumber idea than you did, so quit thinking so much, stay off Twitter, and just enjoy the show.
If you're really in need of some Game of Thrones theories, it's a lot more fun to read the ones strung together by people who don't actually watch the show.
