Some of the familiar scenes included a naked corpse woman dancing in the woods, the craziest looking deer head, and Ash battling against his own hand in what was clearly a thinly-veiled comment about man's own struggles with masturbation. Some of the best new (to me) scenes involved the origins of the Shotgun Hand, Evil Ash, and a timewarp, which I also saw as a comment about man and masturbation.
What's interesting about the first two Evil Dead movies is that how difficult it is to compare the two even though they are relatively similar. One is funnier while the other is scarrier, but both take place in the same cabin with the same evil spirit running around causing all sorts of trouble for groups of frightened woodland tourists. Even with similiar characters and narratives, they can't really be weighed against one another. Maybe it's a monetary. Steven King talked the man who butchered Dune into financing Dead II for 3.6 million bucks while the first one only spent $375,000. For what The Evil Dead did with 1/10 of the money, it's pretty clear which is the more impressive film.
