Good Luck on that! Lol. Seriously though I too wish i could get my money back for Indiana Jones IV. The critics in entertainment weekly gave it 3 out of 4 stars on their rating scale 4 of course being the highest. It is the critics job to tell you how awful a movie is. In the past they had lied about how great Revenge of the Sith was as well.
Recently though Critics May be coming around with their reviews of Clone Wars 2008 movie.
I think critics find it easy to lash out at lucas but they give steven spielberg a pass because he directed Shindlers List, and Saving Private Ryan. When Lucas was responsible for the prequels and Howard the Duck.
And up until War of the Worlds and Kingdom of the Crystal Skull Spielberg made films not videogames, unlike Lucas all his movies starting with Episode 1 look like a videogame.
