Congratulations, I guess.
Seriously though, I never said everyone thinks that way. I said your overall experience diminishes if you know all the spoilers. To say that is not true is a lie. I do not believe you..
I don't know. I almost always read the plot of the movie before I watch it, and I still enjoy it. I also watched at least 4 playthroughs of the first Silent Hill before I played it myself, and I still really enjoyed it.
