I've said this before, but I was a complete BBM virgin when I first saw it. No story, no trailer, nothin'. All I can say is I'm glad that I always carry a handkerchief, cuz I sure needed it. Along with everyone else in the theatre that day.
For the next umpty-nine times I saw it, it was waterworks from the Lake Scene onward, with an extra gasp/gulp at Jack's murder scene.
Now, it's more peaceful and I'm grateful for that. It's like visiting old friends. I tend to see something new each time.
Nowadays, I only watch it maybe once a year.
