“Highway To Havasu” (* out of four) was an excruciatingly unfunny teenage comedy romp about two buddies (Caleb Thomas and Andrew Fromer) who kidnap their broken-hearted friend (Ben Edlin) and take him on a less-than-enthralling road trip to Lake Havasu. Lame writing and direction and irritatingly stupid characters sink this all the way. In desperate need of a coherent script and characters who are even slightly likeable. This unwatchable dreck makes any of the “Porky’s” or “American Pie” sequels look like the Golden Age of comedy by comparison.
