To each his own, I suppose. I was spoiled on about 75% of the happenings in GoT and none of them ended up bothering me, per se, but the ones I was not spoiled on had greater impact. I love a good teaser type spoiler. I just don't get it when people are basically sharing the script, or worse, someone's lame interpretation of it. I find that makes me involuntarily watch the full thing waiting for the next thing to pop up.
But, like I said, as long as they're mostly contained, it'll be OK. What I really want is the digital version to be out already. I intend to watch this movie like 5 times in a row on a loop at this point. I hate waiting for things! But reading the spoilers will mean I'm still waiting for things AND ruining the movie a little bit.
