Just plain awesome.  Top 5 material.  Game-great!  Voices-not sooo great.  But it doesnt make you not want to play anymore.  I have made it to Chapter 8 so far an am stuck on one of the puzzles.  GRRRR.  But it still keeps me a playin'  Go buy it if you love a good story to unpuzzle.  If not...go die then.
