13 Hrs is a horror film that juxtaposes a supernatural creature, the werewolf, and the monsters within, namely resentments and grudges that the characters in peril have been clinging onto, which all come to the surface when they are put under duress.

The film begins with Sarah Tyler (Isabella Calthorpe) returning from LA to her home in the English countryside to find it in the middle of renovations. The old house is in need of much repair and she soon discovers that her parents are in financial difficulty. While a storm brews outside, she catches up with her brothers and friends in the barn, where a bit of a party is underway. The frivolity is short-lived, however, as they experience a powercut and decide to take shelter in the house. Little do they know, they aren't the only ones with that same idea. Before long, they realise they aren't alone and must learn to work together in order to survive the peril that lurks in the shadows.

The movie suffers, in places, from forced dialogue (characters referring to each other as 'brother' and 'sister') and unconvincing acting, particularly in an early scene which is meant to showcase each of the character's personalities. Though admittedly a lot needs to be achieved in this scene in terms of making the audience bond with the characters and therefore care about their fate. It is Tom Felton (Gary) who truly shines here, portraying the try-hard lad. He is both hapless and lovable, a little crude but very real.

Isabella, as the lead, carries the film marvellously, and it is through her character, Sarah, that you really see the story unfold. Her personal journey and the discoveries she makes are poignant not least because of her own fate.

The werewolf isn't seen often but lingers more as an unseen threat, with plenty of fake blood and corpses to create a chilly atmosphere. The story does take a few twists and turns, but most are apparent before they happen. Although one death in particular drew a rather big laugh from the audience, which I'm not entirely sure was the intention of the director.

The story ends with a cliffhanger and plenty of scope for a sequel. With a better budget and a longer shooting schedule, I think a continuation of the story could better its predecessor.
