I wish I could give you a million claps for this paragraph. I've got an article I'm submitting to Cinemania on this subject soon as well.

I am so, so sorry this film was spoiled for you. Nigh on unforgivable as far as I'm concerned. If you were to torture me for information, I reckon I'd resist physical pain, but threaten to spoil a great film and I'd crack.

I jealously guarded my children from spoilers from the likes of The Sixth Sense, Les Diaboliques, The Usual Suspects, Planet of the Apes, The Empire Strikes Back, and so on, so when they were old enough they could enjoy them properly.

At any rate, a great article, and I agree 1000%.
