I have only seen 6th Sense and not the others. I want to see Signs. As I understand from my readings about the director, he is a converted Catholic and is weaving his questions/beliefs of religion into his movies. It is good to ask questions. Dean Koontz's latest novel -THE TAKING - is along this theme - a merging of science fiction with religion. It is spooky and makes you think - something good entertainment should do.
Agreed.
BTW, The epilogue of The Taking was TOTALLY unexpected - an interesting spin on a "well known" event.
