You might not get it...
If you've seen the movie there are a couple of different ways you could have felt about it.
If you've had "the enlightenment" (and if you haven't had it yet then you won't know what it is" then you can see all the issues characters had as the movie reached its conclusion.
If you haven't had the enlightenment, then you will be satisfied with the movies end, believing that the characters all found the resolution. The ending might therefore feel confusing. But if you've had the enlightenment, then you will leave angry at some decisions made by characters, and hopeful about the ending.
WE HAVE FREE WILL.
