A userscript or greasemonkey script that shows the metascore of movies and games from Metacritic.com on several other websites like amazon, google play and others.
It's primarily designed for Firefox and Chrome with
Tampermonkey 
or
FireMonkey .

Tested with Firefox/Tampermonkey and Chrome/Tampermonkey.
