A terrible Hollywood movie saved by its ending

Rating: 6/10 (5 September 2017)

The novella had been noted numerous times when discussing the inspiration for many titles in the industry, I had no interest in watching this film until many regarded this film to have the most depressing/disturbing ending.
Being one who finds interest in being disturbed/depressed, I was intrigued to watch this film.
The film displayed its quality through its cinematography and camera-work, which was very note-worthy. However, this aspect diminishes as the first act ends.
The first issue I noticed was the acting and casting choices, I'm fed up with big Hollywood films always choosing the 'hottest' actors to play the most mundane roles. And that proved to be a great offender for this film.
The acting for the majority of the film is terrible, the only exception being Toby Jones's performance which fit his role. Every actor didn't display much emotion in their face especially when in the most deepest emotions a human could be.
The visuals are very bland, the typical Horror colours are utilised. Although the biggest drawback to this aspect are the CGI effects, which aren't convincing and look abysmal. Some of the CGI effects don't include any lighting to blend the CGI in with the environment, leaving the effects to appear non-existent in the scene.
There are a few practical effects that look convincing, however they're barely in the film, and become very noticeable due to the terrible contrast between the CGI and practical effects.
The biggest offender to me is the script, the characters have barely any character development, so your investment and care in them are nearly non-existent. In addition to this, these characters make the most inhuman decisions they could possibly make in the context the film displays to us.
All of these aspects helped create a dumb Hollywood film that was unintentionally entertaining, the dumb decisions and actions that took place in these scenarios made the film hilarious and annoyingly dumb. The stale, unrealistic, and synthetic acting ensured hilarity in the scenes that attempted relate-ability and emotion.
However, despite the overwhelming amount of problems the film redeems some of its problems with its twist ending, the music and tone is perfect for the situation. The ending was what saved this film from being an unintentionally hilarious Hollywood horror.
