I always thought it looked extremely boring, but one day, for the lack of better software to get, I got it still. The whole atmosphere and chill the game had was a very pleasant surprise and is unmatched by any other Wii game I know to date. The music especially helped create that feeling -- Hayley Westenra's "Prayer" matches the diving sessions in a hauntingly beautiful way. Now I know the soundtrack covers a lot more songs than just Prayer, but they fail to amaze me the way this one did.
All things considered, though, and no matter how enchanting the atmosphere/music was, I hate to say this, it was a pretty damn boring game.
Here's a link to the game's main theme:
