This Z-grade comedy centers on an aging slacker who sits around dreaming up doomed ideas. The movie could be one of them. Consider the producers’ decision to cast Jon Bon Jovi in the lead role. The rock star has held his own in dramatic parts (U-571), but he looks dazed in a comedy. Not that this really qualifies as a comedy, considering the funniest “pro” on-screen is David Faustino (Bud Bundy of television’s “Married … With Children”).
