I am relieved to know that other people found The Visitor as confusing as we did. Over the years, whenever my husband and I have had some reason to mention this movie, we always call it "That weird movie with Jesus in a turtleneck." We spent hours afterwards trying to understand the plot; we never got as far as even trying to understand the meaning.
We went to see because it had such a good cast. The previews suggested it had a supernatural theme, which appealed to us. It was a mistake. We should have stayed home and rotated the mattresses.
I can watch really bad movies without a shudder. I even rather like very bad movies. But The Visitor is in a class by itself. It made absolutely no sense - none. I have read that part of the problem is bad editing. I would hope so. I hate to think that so many fine actors would waste their time on this mess as it is.
