Wow, the awards are well deserved!
The constant camera movement is consistently great, adding not only visual interest, but conveying the idea of "driving" incredibly effectively. The story itself is very interesting, beginning with the premise of a man that knows when he will die, then allowing us along for the ride as he leaves the world.

As a Christian, I naturally have very strong views on death and the afterlife, and this film did a great job telling the story, including the final twist, with a universal appeal. Since it avoided any particular position on the afterlife, and ended up flipping the religious imagery on it's head with the ending, it remains inoffensive and enjoyable by all.
A wonderful film, thanks for sharing!
