deliverance be one of the best exploitation film to come out of that wonderful 1970 decade from whence so many other exploitation film come . a group of friend set out on a canoe trip down a river in the south and they become victimize by a bunch of toothless hillbilly who pretty much try to ruin their life . it awesome . we be treat to anal rape and vicious beating and bow and arrow killing and shooting and broken bone and etc . a lot like 1974 texas chainsaw massacre and to say that deliverance be believable would be immature . this would never and could never happen and even in the dark age of 1972. deliverance be a very entertaining ride and pack full of action . it be one in a huge pile of exploitation film to come from the early 70 and it ( arguably ) sit on top of that pile with it great act and superb cinematography and excellent writing . positive and kid .
