In a twisted sort of way, Charles. Sure, he's a complete asshole and deserves the death he gets, but he's also one of the few people who manages to bring any life to the film's middle section. He's also the only character to portray any kind of Genre Savvy within the movie. In his own jerkass way.
Jason (played by Kane Hodder) chases the protagonists to a diner, where a huge chef tries stop him and gets thrown across the room for his trouble. Actor playing that huge chef? Ken Kirzinger, the stuntman who would later replace Kane Hodder as Jason in Freddy vs. Jason.
This wouldn't be the last time Kelly Hu would appear in something with Jason, as Mortal Kombat X had her voicing D'Vorah, while Jason himself would show up as a DLC character, therefore allowing her to have a rematch in a way with Jason.
Tamara's death. She can only helplessly watch as Jason picks up a piece of a broken mirror and get closer to her.
Eva's death, because Jason forgoes using any weapons and strangles her with his bare hands. It's not the most bloody death in the movie, and while Jason has used his bare hands before, it just seems to take so much longer than the other deaths, and Eva is forced to look into her killer's eyes as she died.
The Scrappy: Rennie, who is often considered by fans of the franchise as one of the worse final girls in all the movies. Sean is similarly considered to be one of the worst of the leading men, with only Rick from the third film providing any real competition for last place.
Sequelitis: This film tends to be the one most often pointed to as the worst film of the series. Whereas the other unpopular entries in the series tend to be disliked for one particular reason — A New Beginning for having Roy as the killer instead of Jason, Jason Goes to Hell for screwing around with the series' continuity, and Jason X for its absurd "Jason in space" premise — this one tends to be considered much more of an all-around failure, in addition to missing the potential of its premise.
Also, because so little of the movie actually takes place in Manhattan, it's often mocked with alternate titles like Jason on a Boat or Jason Takes Vancouver.
So Bad, It's Good: Jason Takes Manhattan is a cheesy late eighties sequel, featuring Jason coming back with rather convoluted means, which also has him being some sort of teleporter who can appear before his victims after they have outrun him.
The Woobie: Renny, like her or not, it's hard not to feel bad, do to her fear of drowning, which the Alpha Bitch uses to get back at her for no reason, and The Reveal that Charles is indirectly responsible for her phobia, do to almost drowning her in an attempt to teach her how to swim. Later, she is drugged by two thugs, who would have raped and presumably killed, if not for Jason showing up.
