Dark Places (like a lot of movies, I guess) won't be everyone's cup of tea as it's a pretty slow-paced Thriller that concentrates on a decent cast delivering a good story. If you're more into faster-paced films then you more than likely won't enjoy this.
The story sees Charlize Theron play Libby Day, a young woman who believes that her brother brutally killed her mother and sister when she was 8-years-old. When Lyle Wirth (played by Nicholas Hoult), a member of a crime investigative group, manages to get in touch with Libby, and starts to provide possible evidence on what actually happened, Libby starts to doubt her own recollection of what actually happened that fateful day.
The story may sound a bit dull & unoriginal, but it plays out better than it initially sounds, and it also gets better as it unravels. It's also a story that you have to pay attention to, especially with the flash backs as there is no immediate indication the flash backs have started (but it doesn't take a genius to figure out when a flashback scene is being played). So, with the jumping back & forward from past to present, you do need to watch it carefully to get what is fully going on. Also, while there is no twist as such, the story does keep you guessing as to how it will pan out.
The cast all do a decent job with their individual parts as well, from Theron's performance as Libby Day, a woman who finds it hard to trust anyone and has become a bit of a recluse, to Chloë Grace Moretz's performance of a young manipulative Diondra. Put a decent cast in to deliver a decent story and you have yourself a pretty enjoyable movie.
As I mentioned earlier, it is a pretty slow-paced Thriller, and while I don't mind watching these, there were a few scenes where I thought it dragged a wee bit, but for the most part it is interesting and enjoyable enough.
It's not the best film you'll ever see, but Dark places is a good film that is definitely worth a watch.
