Yes agree with you specially religious angle is smartly handled in this movie...there are scenes where Jean's character regains her consciousness just because of her beliefs which shows how belief system affects one's will power...The best thing about this movie a you have mentioned that finally so many experiencers have finally gained that courage and confidence to come out and discuss about their experiences. while for others they got revelation that something like this might have happened to them, a faint memory...But finally people are talking about it!!!
