Query: Jack Bull

JACK BULL is a smart and slick tale of frontier justice taken to extremes. John Cusack nails the role of the horse trader done wrong and the acts he takes in retribution.I especially liked the introduction of the John Goodman character as a no-nonsense frontier judge whose sense of justice is equal to Cusack's. Cusack's acts of vigilante justice work on an individual basis in a lawless society, but Goodman represents the Law. I thought this interesting story became fascinating after Goodman's arrival. What started out as a revenge movie slowly and surely morphs into a tragedy, with two strong-willed characters whose passion for justice negates any other considerations.This one surprised me some. JACK BULL is a minor classic and immensely enjoyable. I very strongly recommend it.
