For this movie review of “Good Luck Chuck,” The Dude on the Right saw so much potential for this movie wasted by the movie folks who just made it crude and rude. Jessica Alba was cute as Cam, and Dane Cook did okay as Chuck, and when they were just trying to be in love The Dude thought the movie was cute. Then came Dan Fogler as Stu, Chuck’s buddy, who brought a grapefruit into the mix, and suddenly the movie veered into crude territory it didn’t need to find. Too bad.
