If you didn't like this movie...
You probably were not paying enough attention to the story. I just read through pages and pages of people complaining about "plot holes" and it's clear the details shown in the movie were missed by them. A shame, because it's a good movie even though a bit "romanticized".
Seems some people expect a documentary when they watch a fictional story... even documentaries get some details wrong.
Anyway, the point is if you're going to complain and call it a terrible movie, at least know what you're talking about.
