“Green Is Gold” (*1/2 out of four) was a well-meaning but drab melodrama about a teenage boy (Mason Baxter) whose father goes to prison and he is subsequently sent to live with his older brother (Ryan Baxter) who introduces him to the world of both selling and using marijuana. Despite the movie’s good intentions, both “Half Baked” and “Pineapple Express” were better (and more entertaining) movies about the marijuana trade. Older brother Baxter also wrote and directed this trifle but results are less-than-intoxicating.
