“Marfa Girl 2” (* out of four) was a torturous sequel to the equally awful 2012 drama that focuses on an aimless 16-year old (Adam Mediano) who spends his days skateboarding, having sex, arguing with his girlfriend, and thinking about escaping the confines of small-town Texas life. Don’t look for any more plot than that or anything else either. Yet another unwatchable smorgasborg of sex, drugs, and debauchery from director Larry Clark but this makes his 1995 “Kids” look like “Titanic” by comparison.
