Reviewers need to worry about getting hits and turning their review into a story. Also someone who's willing to spend their time reviewing games probably likes gaming more in general, but has different standards. I.e. someone who likes a main stream band, vs. the hardcore fan that likes obscure sub genres of music.
Amazon reviews can also change with time. So when a game first comes out it could be new. But amazon customers can continuously review games. There are also a lot of fanboys. I.E. PSP GO got 2 reviews of 0/5 before it was released.
I guess it also depends on the amount of reviews in metacritic vs. amazon.
