Too sad and full of regret to do anything. Ever feel like that? Take my heart, it's broken and in a sense betrays you? Do you sometimes feel haunted by regret and despair? We all get sad from time to time, problem is when it becomes dominate.
I find it interesting how the three main actors have become their characters. Rupert is a child in adults shoes, Emma went back to school after filming, and Dan is a slightly awkward man who does what.
