UNBREAKABLE would be there, but for the "captions" about what happened.
They were not there in Shyamalan's original cut, but after test screenings, audiences said they wanted to know what happened to SLJ's character, whether he got away with it or what, so they added in the titles. I don't mind them, when my sister first watched the film with me, she asked me if it was based on a true story, and my nephew and I had a good laugh at that, then she realised what she was saying, haha, but it was because of the titles that she asked that, as they usually only come up at the end of a film that was based on a true story(although they appear at the end of American Graffitti, those characters are very loosely based on real people Lucas knew, I'm not sure if those character's futures were true events).
A Clockwork Orange is probably my favorite. No need for an explanation of why that ending is so fantastic.
Aye, it is quite funny, I think it's better to keep Alex's future ambiguous, so it's better than the ending in the novel, where we later see him talking to one of his old reformed droogs, and saying he has been thinking of living a normal life, starting a family and stuff.
I read, or heard, somewhere that Kubrick was unaware of that ending, as it was not in the American edition he read, I don't know if that is true, surely he would have heard of it somehow, so i do imagine he would have chosen to ignore that ending anyway, to keep it ambiguous.
