Presented in theaters in "4D" - which involved scratch-'n'-sniff cards coordinated to certain moments in the film - the latest adventure in director Robert Rodriguez's family-friendly franchise casts Jessica Alba as a former spy who brings her new stepchildren along when she's enlisted to stop an evil genius (Jeremy Piven, "Entourage").
Trust us, parents, you won't miss the "4D" in the scene that involves the dirty diaper. Alexa Vega and Daryl Sabara reprise their earlier "Spy Kids" roles, and in a nod to another Rodriguez movie, Danny Trejo appears as "Uncle Machete." DVD extras: "making-of" documentary; audio commentary by director Robert Rodriguez; deleted scenes. ** (PG: P) (Also on Blu-ray and Movies on Demand)
