I have built 2statereviews.com with Darren Watt.  The site is based on Darrens long time Film reccomendation system which has only 2 states See! or Dont See!.   Simplicity at its best, the site allows you to search for films and vote See, Dont See for them, warning though its quite addictive.    The site is currently 80% feature complete ( this figure changes constantly as we make up new features).
