Well, it scared Cootie and me, anyway. We don’t frighten easily by any means, but we had to watch an hour of Family Guy after the movie ended just so we could calm down enough to go to bed.
I can see the other side, too. It’s understandable to me how someone could not buy the central premise of Insidious and think it was just ridiculous. I bought the idea, obviously, and more than that, I think it is a movie that bears discussion from a spiritual vantage point, particularly for Pagan households. We’re more into that scene than most Christians, I’m pretty sure.
