For any fans of superhero comics, "Unbreakable" is a fine, absorbing film, I rate it among the best I've seen.

Rating: Null/10 (27 June 2001)

"Unbreakable" is one of those films you really need to see twice, and not miss even one line of dialog. It is a fairly simple premise, but appeals to me because of my own view of the world being one big statistical distribution of skills. And that is the key point of this story.
Elijah (Sam Jackson) was born with a rare genetic affliction which causes his bones to break very easily, and he is "sick" all the time. Being a lifelong fan of action hero comic books, and thinking they all have exaggerated shreds of truth, passing down fantastic stories much like cave men did with drawings on cave walls, he figures there must be someone else around who is at the other end of the "distribution." Someone who is "unbreakable", who has extraordinary powers.
David (Bruce Willis), a university stadium security guard, on the way back to Philadelphia from a job interview in NYC, is in such a terrible train crash that he is the only survivor, without even a bruise or broken bone. Elijah reads this and wonders if he has found who he is looking for. They meet, David is very skeptical, but begins to examine his life. He has never been sick, accidents do not harm him. His only weakness, his "Kryptonite", is his fear of water.
David begins to test his abilities, as bad people brush past him he can "see" their crimes. He follows a particularly bad one, a janitor, who has killed the parents and tied up the children. David trusts his power and fights the bad guy. David realizes who he is, doesn't wake up with the "sadness" anymore, and his wife and son and he get a new start.
As the director explains in the DVD extras, the movie is intended to be a standard comic book episode where the superhero first discovers the extent of his powers, and accepts the role of "superhero." But instead of it being done in an exaggerated comic book style, it is filmed in a "neighbor down the street" style, with an ordinary looking man, with an ordinary job, family, son, and marital problems. I think he pulled it off very well, and makes us wonder if such "superheros" could actually be among us!
July 2010 update: After not having seen it for several years, I saw it again presently. It is a very well-told, nuanced story and a superb film. I believe Shammy's best film, and judging from his recent mediocre movies, maybe destined to be the best he will ever make.
I believe some of the poor "user" reviews are because they expected a certain type of movie, but got a different one. If one accepts that this is a comic book story, and judges it on that, then to me it rates a high "8" or maybe "9" of 10.
MAJOR SPOILERS FOLLOW: The "twist" in this film comes at the end, like in his "Sixth Sense", when we find out, after they shake hands, David "sees" that the train wreck and many other catastrophes were caused by Elijah, in his misguided quest for the person who turned out to be David, killing hundreds, maybe thousands of innocent people. David exposes Elijah who ends up committed. Elijah, the flawed prophet. David, good king.
