In the Marvel thread, most post spoiler stuff in small font for about the 1st weekend / week. Then perhaps a warning for another weekend, then it's fair game.
I'll be avoiding this thread, and FB. I'd managed to be blissfully aware of Han's demise before the release, but then some f'n post in my FB feed on opening weekend spoiled it. jingle.family is going Sunday afternoon, so I'll be off FB for the weekend. No big loss.
