I am so, so very tired of PG-13 teen angst movies adding in a ghost and calling themselves horror films. What "Solstice" does is basically take a bunch of teens who belong (or actually have been) on a silly WB show, adds in a plot that could be a bad episode of "Supernatural," some drunken, preppy, hard to like characters and mixes until you want to punch most everyone in the movie in the face.
This movie is just stupid. The characters are stupid. The plot is stupid. The screenplay is something I would give to my dog to tear up. There is no gore or blood to speak of, the scares are something anyone with one brain cell could see coming, and I wish I could have killed both male main characters within 20 minutes of this movie starting. I am so disappointed Sid Haig was in this film. He really wasn't all that bad in it, but he wasn't given much to work with and he just doesn't belong in films that are PG-13.
It IS possible to make a horror movie that centers around teens, involves the regular angst and shenanigans without traveling down the just plain fucking dumb route this one takes. You just have to look to "Ginger Snaps" (admittedly more complex than just teen angst) or "Carrie," among many others to see this. You can have an intelligent horror movie about teens. I swear to whatever you need me to that you can. It just isn't this.
The voodoo elements of the film were absurdly done, not handled well at all, and quite frankly made me laugh (especially the scene in the water). I honestly wanted some sort of vengeful sea creature to rise up and eat all of the characters so I would be saved from watching the rest of the movie. Sadly, that did not happen and I wasted roughly 90 minutes of my life just so I wouldn't feel bad about writing a review of a movie I hadn't seen all of.
I do not recommend this movie at all (unless you are 12 and having a slumber party). I feel ashamed just for having watched it.
