Though Evil Dead 2: Dead by Dawn could be considered a soft reboot of the first film because so many events repeat, it's got enough going for it to make it one of the most memorable cult horror hits of the '80s. Evil Dead 2 not only led us to Army of Darkness, the quintessential slapstick horror movie every teenage boy loves to quote, but it also laid the real foundation for fan-favorite actor Bruce Campbell's career. Evil Dead 2 wouldn't have happened without Evil Dead, but without Evil Dead 2, Bruce Campbell would have just been that guy that shows up in Sam Raimi films as a friendly cameo, and we probably wouldn't have Ash vs. Evil Dead.
Most importantly though, without Evil Dead 2, we wouldn't have a bunch of kick-ass toys of a dude with a chainsaw for a hand.
