Like Wereallmad said, the simplicity of the plot is a strong point to the game. Similar to ICO, you're treated to heavy intro and ending cinematics that do the majority of the storytelling, but for the rest of the game, you're left to interpret/invent the main character's emotions and psychological state. I'm not even sure how the story could be given much more detail without feeling contrived/unnatural. I also don't think there's anything in the game left unexplained by the ending.
And, regarding the ending, there's one aspect I'd really like to discuss here... But SOME PEOPLE (Aaz and Griff to name a few) still haven't played it, and I know they'd ignore spoiler tags, regardless of how clever they're hidden.
