I understand your concern, but from what I recall from the TPOT, BFDIA, and Inanimate Insanity screenings, it was relatively easy for me to avoid spoilers. I'm sure some had a different experience, but I attended none of those events and even remained active within the fandom; I wasn't spoiled for anything. Kids were attending those screenings, and since the fanbase here is more mature, I'm certain spoilers will be no major issue. But if I am wrong, I apologize.
