This will fetch a metascore from metacritic.com. It requires a url from metacritic without the http://www.metacritic.com/ Example: $ metascore games/platforms/wii/supermariogalaxy - $ metascore tv/shows/marriageref - $ metascore video/titles/newmoon Would be cool to use this in some sort of a graph.
