The main problem with this movie is that it just feels really dull. There is one character in the movie that gets some form of characterisation and actually allows for you to care for them, however, the other 3 have almost no characterisation making it practically impossible to care for them as much as the movie makes you want to. The cinematography and acting is fine, but nothing great, however the direction feels a bit bland. You never really get any sense of tension or stakes and this is worsened by the dull characters. There are several moments I thought the movie could do something unique or clever, but instead it just went along with a plain, almost predictable plot. You can't say you've never seen a movie like this, with several others doing much better. I can't say I hated the movie but it just wasn't anything special.
