Elements of horror are present in both The Descent and My little eye

Both The Descent and My little eye tap into the fear of bring trapped and secluded. They are both cut off from the real world by their own doing. The Descent uses darkness to keep the audience in suspense, waiting for the light to come on so they can see whats happening next. where as My little eye uses pauses and cuts to different camera angles to build the tension. They both have the element of chase in them which picks up the pace of the film and prolongs the inevitable. where the mad man/creatures are chasing after them trying to kill them. The part of the film where the audience knows who's not to be trusted but yet the actors don't makes the audience scared for them as they have built up an emotional attachment by watching the situation the characters are in and almost felling responsible to tell them that they are in danger. And by just the audience waiting to see how they will find out causes the fear in the audience. They are effective horror films because they both have the skill of making the audience jump and be afraid which is what horror films are all about.
