I've never seen The Passion and have no inkling of an urge to.
It's not great fun, and fun is usually what we're looking for in a movie.
That I saw, and I did it because I felt I "needed" to. It was a religious, not an entertainment experience.
I don't think I could watch it again. But I'm glad (well, not "happy glad" but you know what I mean) I saw it once.
I went alone. Mrs. couldn't bring herself to see it.
