What a lot of people fail to realize is that before Peter Jackson was directing epic features backed by breathtaking visual effects, his roots were planted firmly in the splatter genre. His break-out film was the 1987 splatter comedy, Bad Taste. As the title suggests, this film relied heavily on the gross-out factor of his splatter effects for a good laugh. (Good toilet humor, all in bad taste)
Meet the Feebles is like what Jim Henson would see off of a bad acid trip.
Then there was Braindead. Known here in North America as Dead Alive, this film is touted as the goriest film ever made. This zombie horror/comedy features some great lines as well as some of the sickest gore around. A kung fu priest shows up to beat down some zombies while exclaiming that he "kicks ass for the Lord!!" This was the very pinnacle of Peter Jackson's greatness in the splatter genre. Braindead was a laugh out loud, gross humor epic that will be a staple of zombie movie lists as well as cult classic lists for years to come. I've played this for some friends and was told to turn it off one time because she thought she was going to puke.
