I can remember when I was 24, and I broke up with my first serious girlfriend for the first time. She was a very nice person, but she had a little bit of a tendency toward melodrama... Her response was to take the key to my apartment off of her key chain and hand it back to me.
I think 'Manchester' is really about grieving and trying to get on after something terrible has happened to an adult, and a whole life being destroyed, and then, what are the forces that keep him involved with the people he loves? They love him, and they won't let him go.
Many movies about people recovering, moving on, and redeeming themselves are really wonderful and inspiring. But I think the more sentimental ones that are less good make me feel isolated - like, if you can't pull yourself up by your bootstraps like the guys in the movies, there is something wrong with you. That's a shame.
