Sheesh you guys! You didn't warn me it was so intense...but then I don't watch a lot of action/suspense movies. I did appreciate being tipped about the post-credit bit. The credits were long and my son wanted to go, but I told him when they started that there was more and several people around us waited when they heard me say that. I don't normally like Canoe, but his empty, wooden demeanor was perfect for this role. My teenaged son liked it, but I had to feed him a lot of biblical references. I don't think you need to know them for the movie to work, but it does add depth if you go in with some knowledge. I called it "Dogma" with attitude, but my kids disagreed.
