Silberling’s big-screen comedic take on the low-budget ’70s Saturday morning TV series tries hard to throw goofy entertainment your way and fails at virtually every turn. Part of the problem may be that the movie isn’t quite weird enough, so instead of seeming inspired in its dementedness, it just seemed inept and desperate. There is some pleasure to be had from the comical interactions between Will Ferrell and Danny McBride, as Ferrell works his well-honed man-child persona and McBride basically steals every scene he’s in. He doesn’t have much to work with, but he does enough to salvage at least a few scenes from this wreck of a would-be comic blockbuster. (Hollywood Jewel 16, Waco, TX)
