Ever since his bravura underrated performance in 2002's "One Hour Photo," Robin Williams seemed to be back on track to delivering dramatic performances. Unfortunately though, his career took a steady downturn by starring in supremely mediocre comedies including "RV," "Old Dogs," "Man of the Year," and "License to Wed." However in 2009, Williams returned to his dramatic roots in 2009 with "World's Greatest Dad," a dark comedy indie that was a festival hit, but didn't get a whole lot of attention during its theatrical run. Fortunately however, the film has attained a cult following over the years, which it highly deserves because of its no-holds barred approach to the dark comedy subgenre.
