I gave it a 7, because I find some of the relationship dynamics in the movie to be an unnecessary irritation. The movie could have been a masterpiece without the histrionics. Maybe they just didn't ring true, or maybe they didn't add much to the story. Maybe (in the case of the daughter) it was just so much negative-feeling bunk that really distracted. It's too damned bad. This is a large-canvas film and it was diminished. I *think* that's because instead of infusing our characters with some nobility, we were treated to whining, and supposed realistic human behaviour. I gotta say, if you're aiming high, don't sabotage your attempt with the low human characteristics. Give us something to feel good about. This movie seems to be about people attaining their goal despite being 'merely human'. Darned shame, wasted opportunity. I felt irritated often, throughout the movie and didn't feel like cheering, at the end. Great cast, though. Even Matthew McConaughey had his more irritating acting twitches reigned in by Christopher Nolan's directing skill.
