“Bus Driver” (*1/2 out of four) was a dumb-and-dumber horror thriller about a bus driver (Steve Daron) who is a former military soldier whose former skills come in handy when him and his students are stalked and terrorized by backwoods lowlifes when their bus breaks down and they stumble upon a not-so-concealed drug operation. Potentially fun horror show is hindered by cheapjack production and stupid script but at least it moves fast. Robert Forster picks up a few bucks and must have been cast only for his name value because he shows up only in the last two minutes.
