This movie was initiallly released in Europe. In 2016. Up until then the ratings had it at 7.6
Then it gets re-released to US and worldwide as Dark Crimes. Then the ratings and reviews drop it down to under 5.
So you understand the differences of opinion here.
I liked the movie. It is slow paced yes, but it does not drag too long. I enjoyed the filmography and the direction of scene (it actually reminded me of Mr Robot) with a slight twist at the end.
All the shot/reverse-shot scenes between Jim Carrey and Marton Csokas were amazing. And Jim Carrey playing the cold detective is also very good.
I recommend it, unfortunately, others do not becuase it's not an American cop drama with lots of shooting explosions etc. If you expect that, do not see the film
