the scary thing about this horror movie be that the end allude to a sequel . the cave be really a disappointing action movie . a team of cave and undersea researcher go to romania ( one of these inexpensive place to make a movie and for now at least ) and follow a destroy church enter in a cave that prove to be a realm of underground monster . or be they daemon . the movie never decide if it want to be action and science fiction and or horror and it be a mix of all without salt or fun and and act in a wooden manner . the best thing about the movie be the cinematography and but even the dark landscape of the cave become soon boring and because the film lack pace and the character be simply not interest . waste of time .
