“Poor Herman” (* out of four) was a poorly made horror comedy about four friends (Sara Alavi, Punjamean Martin, Fantasia Chattman, Maritza Arenas) who go to a Halloween costume party where they are (yawn) besieged by a deranged killer (Deonitus Phoenix Black) and have to fight to survive. Strains to be hip and stylish but just comes off as low-rent and vulgar not to mention stupid. Co-star Martin also wrote and directed; even at barely over an hour long, this is still pretty rough going.
