Finally caught up to this after all of the Oscar hoopla. Amazingly enough, it's just about that good. I say just about, because there are obvious over-dramatizations of situations and timelines, and not all of the acting is really Oscar-caliber. I think all of that should be expected for a film 'based on a true story'.
Even so, it's a darn good film, with above average writing, acting, and directing. Recommended.
