In the beginning of Dear John (2010), John is dying in a war and he tells us a story about his life.
Here are the first lines from John:
There's something I wanna tell you. After I got shot...you wanna know the very first thing that entered my mind before I blacked out
But the movie ends in a different way, I mean he is not in a war.
Then why are the first and last scene not the same in Dear John?
