Army of Darkness (1992)
The Evil Dead movies are among the greatest Horrors of all time and Army of Darkness was so out there that it became an instant cult classic.
Bruce Campbell (The Evil Dead, Bubba Ho-Tep) is transported back in time, has to fight an army of dead monsters and retrieve the Necronomicon to get back to his own time.
Oh, and he has to do it all with a chainsaw for an arm. Awesome!
This is one great movie and this is my Boooomstick!
