“Kill ‘Em All” (**1/2 out of four) was a diverting, if not particularly original, action melodrama starring an aging Jean Claude Van Damme as a mysterious stranger who arrives wounded at a hospital when a vicious foreign gang shows up at the hospital and attempts to finish the job and have him killed and a caring nurse (Autumn Reeser) is his only ally and source of protection. Nonstop action and some stylish touches from director Peter Malota make this one of Van Damme’s better movies since his ’90’s heyday. If only he improved his acting chops, he might have a shot at a real killer comeback.
