“Eat Wheaties” (*1/2 out of four) was a synthetic comedy about a middle-aged blowhard (Tony Hale) who finds his life gradually starts to fall apart when he tries to prove he was friends with a particular celebrity in college and this leads to his close friends and job to find out that he’s full of it. Failed attempt to cross-pollinate a moral melodrama with sitcom humor; a paper-thin premise stretched well beyond its limits at nearly an hour-and-a-half. Hale tries his best but you’ll likely be starving for laughs and fulfillment.
