“Zoombies” (*1/2 out of four) was a mindless, silly rip-off of “Jurassic Park” about a virus that spreads through a safari theme park and turns all the zoo animals undead as several park workers and attendants must stop them before they escape. Steven Spielberg should probably sue but even he probably can’t be bothered to watch this timewaster. Kim Nielsen is good as the doctor who runs the park but other actors are easily outacted by the zoo animals.
