What  impressed us most about the film is Dr. Fishman and Butch Ryder, the two corpses that Max and Charlie used, they were not really bad people as they thought. 

Dr Fishman had developed a "magic"cancer treatment and started to conduct secret clinical trials, not approved by the FDA, to his friend and great love Bucht Rayder and other people that had cancer, who but when they were discovered they took away the financing
