You can only see it once
See this NOW, in the theater. Don't wait for a DVD or stream it. Pay attention. In the theater you are isolated, there are no distractions. Turn off the cell phone, don't just mute it.
Afterward, you may be tempted to see it again. Don't waste your time, it's no longer a new movie, a new experience.
Many years ago I saw THE SIXTH SENSE in a theater. It was fascinating. It was one of the best movies I've seen. Years later, I saw it at home, on a DVD. I didn't understand what I found so fascinating about seeing it the first time. It was a dull, routine film.
Some movies you can only see once. See it right. I think this is true of all of Shyamalan's movies.
