Obsession is usually a very effective subject for thriller films. Just look at Fatal Attraction and Misery. Unrequited love or an uneven admiration for someone can cause extreme tension and in some instances, danger. The new thriller Missionary takes obsession to new heights and it is a film full of all the creepiness and violence that usually comes with stalker fare. It takes obsession to pretty extreme heights and the results are not only frightening but genuinely entertaining.
