Had “Primal” decided to remain what the show was for most of its first season, it would still be one of TV’s best. It solidified itself as a fascinating spin on the adventure show, a Genndy Tartakovsky-created journey through some of the more ruthless corners of Nature. Burly man Spear (voiced in grunts and screams by Aaron LaPlante) and upright-walking dinosaur Fang made for an on-screen team-up that went from anachronistic to undeniable over the course of its first ten episodes.
