I felt exactly that. I think I felt hot, but I couldn't remove my jacket, because I felt cold at the same time. I was moved to tears several times, which is rare for me. I would start suddenly, then stop almost as suddenly. And what I sensed is that different people were moved at different times in the movie. The different experiences were what made it private. Everyone's tears were his own, a reaction to something that led to introspection.
Liz, #404: "The story is universal and is meant to mirror humanity."
PleaseNoMore, #399: "I also noticed that no one looked anyone in the eye. Each person was internalizing what they had just experienced."
SoDak, #424: "Neither of us could even talk about it afterwards...I'm amazed, numb, sorrowful, and kind of elated."
Liz, the word "mirror" says a lot because the experience of the Gospel as depicted in the movie is so personal. Maybe that's why so many are describing being unable to carry a conversation afterwards. People feel stunned, numb, maybe even physically sick. But underlying it is the sense of "elation" or hopefulness. Some have said the movie ends too abruptly. I think that's what Gibson intended. We don't need to see the extended reactions of all the characters (we sympathize with the "good" and "bad" both) because ultimately the viewer's personal reaction is the one that endures. An inability to internalize is what prevents some from experiencing the fullness of the message.
That was my reaction exactly. On the drive home, at the deepest level, I felt strangely elated.
