Yep, that's the best of the "Evil Dead" franchise. I'd also include as an obvious cult-film, the 1978 update of George A. Romero's zombie genre, Dawn of the Dead. It was frequently run as a "midnight movie" back in the early '80s. It pulled that genre out of the black-and-white past and into vivid, gory color.
And who could forget the "Helicopter Zombie"? Any scene that could provide a then-unknown and uncredited actor with a lifetime of convention fame - that has gotta be a cult film.
