“Die Hart 2: Die Harter” (*1/2 out of four) was a mindlessly dumb follow-up with Kevin Hart once again playing himself and trying to cement his legacy as an action hero by planning an action film with unscripted and unexpected scenes but he soon falls victim to a plot featuring a former cohort (John Cena) from the past. One-joke movie with only Hart’s good-natured comic persona to carry it but runs out of steam (and laughs) very quickly. Cena’s terrible wig is almost as funny as the hilarious title.
