The Ruins : some half-n-a-k-e-d teens go to a south American pyramid and enforced to remain there by locals, soon they will know the reason : they have touched a dangerous meat eater plant.
the movie has not something special, only some fresh skin and some blood and meat, the scene where the boy cut his friend's legs by a stone (to break the bone) and a small knife (to cut meat) is horrible along side the girl who butchered her self.I am sure the Stephen King's story is better than the movie.
Mirrors has better story, although it has a lot of blood in it, evil reaches this world through mirrors or anything reflected like a mirror a man with no bright past and in danger future find's out that something mysterious happens about the mirrors in the building he works and outside of the building, the evil spirit in the mirror kill people by doing something to the reflection of those people, trying to find "Assaker" (or something like that) which is a girl's name that everything is starts with her.
the best scene is the last scene : the man gets out from ruins and finds himself mirrored, every thing appeared like they are being seen through a mirror, now he become a ghost in the mirror.
