I started out, before I saw Sideways, as a skeptic of Giamatti's talent. After that film, I had to make a 180 on my view. He was exceptional. I've liked him a lot in most everything he's been in, but a Hawk is Dying is a work that I am sure he will always remember. This was a perfect film for his unique, everyday man, with enormous depth and complexity (like most of us everyday people).
In this film, he and most of the other characters, give exceptional performances, in my opinion, because this was a small film. This film didn't have to conform to the Hollywood formula, so that millions of people can understand the plot, and get excited about the action or the comedy. This film was made for a smaller audience that likes to be treated like a thoughtful person, and enjoys escaping into another world. What this film did well was draw the audience into a world that it might never have seen, but it can identify with.
I would recommend this film. Watch it without distraction and let it take you into a very interesting and captivating story about love, compassion and the frustration that comes with giving of yourself and then facing those others that did not, and will never understand what you have done. The complex emotions come through, without hyperbole or obvious references, inserted to make sure we don't miss the point. This is true film, a window into life experience, from other humans, like us, who live and feel and hurt and struggle.
