The Plucky Comic Relief Chewie has been well-received by critics who gave this film both positive and negative reviews, some considering him to be one of the most likable characters on screen and having a "memorable death."
Older Than They Think: Jason being a cunning and agile killer unlike the supernatural zombie Jason, which is what the audiences are most familiar with. The original Jason was also fairly cunning and had at least one instance of using a trap to kill his victim (a snare trap to allow him to calmly walk in and slit a throat, in his very first film). It was after becoming undead that he became more of a blunt instrument.
Absolutely no one likes Donnie, thanks to his asshole behavior and creepy sexual interests. He's also something of a Replacement Scrappy for Shelly from Part 3, who provided Jason with his signature mask and is a well-liked character among fans for being enjoyable comic relief. His death by Jason's hands is seen as very cathartic.
Also Whitney, whose boyfriend and friends were killed and herself later is kidnapped and held a prisoner by Jason.
Clay, his sister goes missing and when trying to find her with his friends they all are killed by Jason, including Jenna, the only one who listened to him and was willing to help him as soon as they were about to escape. What's worse is that he finds out her sister was kidnapped by Jason and in the end, just when everything seemed fine he has to witness her sister who he tried so hard to save possibly die from a not dead Jason possibly leaving him the only survivor. Poor guy...
