Watching this film all the way through is a bit like playing a video game with a ridiculously hard end boss. You're enjoying yourself for the most part, but then you reach the climax and the fucking bastard just won't die. So you slog away, ignoring your mum's calls to lunch and dinner. Finally you hit the right combination of buttons and he dies! Having not eaten or showered all day suddenly doesn't seem worth it. And all you've got to show for it is more lost childhood and a really sore thumb.
