Yeah, certainly it represents not a mainstream movie, also not a masterpiece. But, if you need to spend almost 90 minutes of brainless time this pseudosequel is good. The protagonist, Sasha Mitchell, plays good his role of cruel cyborg teacher, killing and destroying all things he hates around him. In fact, the scene of the incipit (with a school gang burned in a car) shows up it all, exploding in a gratuitous exploitation. Have a nice vision!
