“Monster Trucks” (** out of four) was a heavy-handed children’s action comedy about a small-town kid (Lucas Till) who builds a “monster truck” from scraps and pieces of cars and a loving subterranean creature ends up invading the car and helping it to come to life but corrupt law enforcement and business officials (Rob Lowe, Holt McCallany, Barry Pepper) end up in pursuit. Silly story moves fast enough but lacks the magic and spark to make it take flight. Ironically, the film itself seems built from scarps and pieces of other (better) movies like “Short Circuit”, “Transformers”, and “Herbie The Love Bug.”
