Knuckleball does not flutter; its pace and tone is lean, mean and eerie. Luca Villacis plays the home-alone little hero, a Rambo MacGyver Jr. in the making. Not all the kid’s ingenuity and wits are plausible, though, and a late-plot throw-in is a bit much. Still, there’s Ironside and enough cold-weather tension to make Knuckleball a swing-and-hit deal.
