“Mortal Kombat II” (** out of four) was a curiously bland sequel about the group of warrior champions (Adeline Rudolph, Jessica McNamee, Mehcad Brooks, and others) who are now joined by Johnny Cage (Karl Urban) and are pitted against one another to stop the world domination threat of Shao Khan (Martyn Ford). Full of the usual martial-arts mayhem and hand-to-hand combat but it all seems pretty by-the-numbers with one-note characters and a paper-thin script that don’t do the video game justice. Enough to satisfy long-time “Kombat” fans but others will likely want to press game over.
