There was nothing they did that caused you to be alarmed. They were pleasant, engaged and most importantly attentive to your friend. Though the two of them had been dating for a few months, this was the first time you were meeting them. This was known as moving the relationship to the next stage, where it was time for the boyfriend/girlfriend to meet the best friend. Hoping to keep the get together as stress free as possible, it was decided that everyone would meet for lunch; nothing else was planned in case by some small chance there would be any kind of friction between the two. In spite of everything going well, there was something about them that set off a tiny alarm in your head. You could not explain it but you had a sense that something was not right about them. The tough part was deciding whether you should tell your friend about your feelings; it was a no win situation. Though there would be several more get togethers, you were always on guard; looking for something concrete you could casually bring up to your friend to see how they would react. You were smart enough to know when a friend was involved in a relationship it was your job to be supportive and not say anything unless something blatant was being done by the girlfriend/boyfriend. HESITANT at first, the Peterson family quickly opened up their home to the stranger David, played by Dan Stevens (A Walk Among the Tombstones, Hilde), when he explained he and their deceased son had been friends in the military. With Laura and Spencer Peterson, played by Sheila Kelley (Matchstick Men, One Find Day) and Leland Orser (Independence Day, Taken franchise), insistent that David stay with them for a while, it was soon after he had settled in that a couple of accidental deaths occurred. This film was a surprise for me with it retro vibe and fun script. Dan Stevens was so good in the role; he easily commanded the viewers attention. Like those scary thrillers from a decade ago, the tension came more from the chase instead of the violence. Now granted there were a few violent scenes with blood, but they were almost minor compared to the buildup. Another aspect of the movie that i enjoyed was the script; it had a fun dose of cheesiness, yet made the characters real to the point where I was feeling concerned for them. In addition, just when you thought the story was going in one direction, it veered off in another direction. This sounds strange to say but I really had a fun time watching this film, despite my initial wariness. A few scenes had violence and blood in them.
