I liked it!
What, you want more? Ok!
This movie isn't really a remake of the original. It's a retelling of the series, with elements from several of the movies. Rather than being an origin of the slasher we know (and love) as Jason, the new Ft13 gives us a brief bit of history (basically the final confrontation with Mrs. Vorhees in the original) where we get to see Jason discover his mother's dead body. We also hear Mrs. Vorhees' voice whispering in Jason's head to punish 'them' (if you don't know the history of the series you might not realize that this means horney teens, because you might miss her explanation of why she's killing people).
Cut to something like 20 years later. We get a long extended scene where we meet a group of campers who are exploring the woods near Camp Crystal Lake in search of some marijuana that is supposed to be growing in the woods. All of these characters lack any memorable qualities to them other than Whitney, who ends up being a major character. We get to watch Jason butcher all the campers, right after some gratuitous sex (because all 80's Slasher-flicks need gratuitous sex... I think there's actually a law somewhere demanding it). The screen fades to black right as Jason is about to strike Whitney, leaving her fate a mystery, and cutting to the title of the film.
Six weeks later...
A group of kids (maybe teenagers, more likely college students) are going to spend the weekend at "Trent's" family home in the woods (across the lake from the abandoned Camp Crystal Lake!!). Trent is a major asshole, and we get that impression right from the beginning when he is waiting in line to pay for his gas and starts bitching because Clay Miller (Padalecki) is talking to the cashier, trying to hang a flier for his missing sister, Whitney (see how that all ties back around?). Trent tries to claim that Clay is an "asshole" because he's stopping him from paying for his gas and going. Clay stays very non-confrontational and does his best to ignore Trent. Trent's girlfriend, Jenna, sympathises with Clay and gets pissed at Trent for they way he's acting.
Clay continues travelling around the area, trying to ask locals if they've seen his sister. He has an encounter with the local sherrif who tells Clay to give it up; they've already searched for Whitney and her friends, and turned up nothing. The sherrif thinks maybe she ran off with her boyfriend. Clay protests that Whitney wouldn't do that; their mother just died of cancer, and until this trip Whiteny took care of her every day. When Whitney didn't show for the funeral, Clay knew there was a problem and came looking. Clay continues his search, with no luck, though one local tells him that "missing" in this area means "dead" and he should just get out of there while he still can.
Trent & co get to his house. We soon discover that Trent can't really stand his "friends" and that he basically invited them for the weekend so he could show off how rich his family is. He tries to convince Jenna to go have sex with him, but she's not up for it; she'd rather go hiking, and she's pissed at the way he's treating everybody. (Side note; Trent is played by "Travis Van Winkle"... his name even sounds like a rich asshole's name! He looks the part too, and every movie I've seen him in, he's an asshole... talk about born to a role...)
Two of Trent's friends decide to check out the other side of the lake, and Trent lends them his car to prove that he can be nice to everyone... then he asks them to take gas to the family boat and threatens his friend if they take the boat on the lake. The pair leave and immediately make plans to go water skiing. Clay shows up at the house, still looking for Whitney. Jenna invites him in to get something to drink, but Trent throws a fit. Jenna, now completely pissed at Trent, offers to go with Clay to the other side of the river.
As the two walk we learn that Clay and Whitney have had a major falling out; Clay skipped out on his family when he was 17, and the last time he and Whitney spoke they got into a fight. Guilt is part of what's motivating him to look for her.
Meanwhile, remember the two idiots who went along to the other side of the lake? Well we get to see more gratuitous topless scenes (note: in a Slasher, topless means "we're done with you, time to die"). The boyfriend is shot in the head with an arrow (I love that part, he even turns and "poses" for the camera), and the girlfriend is clipped by the boat. This doesn't kill her though... we save that for Jason, who stabs her in the head with a machete (another nice death scene).
At the camp Clay and Jenna get the creeps while exploring the place (it's night now, and the place is ruined... a natural reaction). As they leave they spot Jason coming into the camp and hide. There they realize he's carrying a dead body. Jason realizes that someone is there, but can't find them. He goes on to the caverns he's using as his home while Clay and Jenna flee back to Trent's house. Down in the caverns we discover Whitney alive and chained.
Confused? Well, that's because I left something out... Whitney resembles Mrs. Vorhees in her younger years. Jason's being sentimental because of the resemblance. It's mentioned early on, I just didn't feel the need to say anything.
At Trent's house Trent and his friend Bree have decided to go have sex (woo hoo, the asshole is real faithful to his girlfriend). This has some great dialogue... ok, not great but it's funny because Trent can't stop saying how great Bree's breasts are (yup, more gratuitous sex!).
Clay and Jenna arrive, Jason following, and the killing begins. First he kills off two of the other friends (I haven't mentioned them yet because they're really not that important... which is unfortunate, because they're the token Asian and Black Guy you often find in these films, and they really could have been made into much more interesting characters). Then, while Trent is yelling at Jenna for being gone 8 hours with Clay (he claims they've been having sex all over the woods), Jason kills Bree. Trent goes for a gun, but starts shooting everything. The sherrif shows up... and Jason kills him. Trent, Jenna, and Clay make a break for it. Trent dies. Finally.
Jenna and Clay make it back to Camp Crystal Lake (minor nitpick... it's still night, but the way they've made things sound it takes a few hours at least to get there... wouldn't it be daylight by now?) and discover Whitney. And then....
Nope. Not doing it. See the movie.
(Here's a hint. Remember the VERY END of the original? When Jason jumps out of the water and grabs the girl in the boat? Last scene is an homage to that, but different in its own way.)
Like I said, I liked it. It has some story issues, but most slashers do. And we don't watch slasher for the story so much. We watch them because we like the villain, we like the violence, and we like the gratuitous chest shots! This movie gets about 4 out of 5 from me. Give it a chance, it makes for a great entry point to restart the whole series with fresh material.
End of Demented Rambling.
