Granted, Evil Dead II is not everyone's cup of tea. If you hated the first film, you will most certainly hate the sequel. There is more blood squirt and demon ooze projected in Evil Dead II than a thousand Exorcist movies. How they got this one past the censors in 1987 simply baffles me. But even if you dislike this kind of film, you cannot deny the unique vision of Sam Raimi who inspired a number of modern horror filmmakers. Evil Dead II is that rare breed of horror films that dares to be as gut wrenching as it is funny. This is no easy task and Raimi pulls it off flawlessly. I dare you not to feel exhausted after watching this film. There is so much going on in terms of inventive effects and sight gags that repeated viewings are absolutely necessary to appreciate everything Raimi and his effects gurus bring to the table. [Watch the "making of" featurette on the DVD to learn how they made this film come to life. It's quite fascinating and a tribute to the incredibly talented people who worked on this film.]
If you're idea of a good time is watching The History Channel, then skip Evil Dead II. If you have a strong stomach, a twisted imagination and like your humor very dark, then this one is tailor made for you.
