“Zombieland: Double Tap” (** out of four) was a mindless sequel to the 2009 comic hit featuring the survivors from the original (Woody Harrelson, Emma Stone, Abigail Breslin, and Jesse Eisenberg) moving to the American heartland as they have to face off against an evolved breed of zombies that threaten society as we know it. Director Ruben Fleischer employs the same in-your-face action, comedy, and stylistics from the original but it feels like an unnecessary retread and runs out of steam after a while. Harrelson’s gonzo performance and good chemistry between all of the leads give this as much fuel as it can but it still mostly fires blanks.
