“Deadlocked” (*1/2 out of four) was an enervatingly predictable and derivative zombie-shocker about a group (Taylor Tunes, Nick Champa, Kyle English, and Sophie Giberson) who are trapped in an elevator in the midst of a zombie virus and soon realize that one of them may be a carrier and they have to race against the clock to find out who and also to prepare themselves against the ward of zombies that awaits them outside of the elevator. Potentially intriguing story and idea is itself deadlocked by its own familiarity and cliched characters. Sadly by this point, there may not be much new that filmmakers can do with films about zombies and viruses.
