Don't believe these good reviews, at best this movie is mediocre. I'll save you some time. This movie consists of 30 minutes of running and 40 minutes of illogical decisions.
It's full of plot holes. There's seemingly only 2-3 police officers working in this city, they discover a whole crime scene yet let everyone walk away. Later on at the police station there's a scuffle between the brazen killer and the victims brother in which the police could not differentiate between the two, and instead of keeping both parties at the scene the killer is allowed to leave.
Don't get me started on the killer, I did not know they casted Usain Bolt, this man is running a marathon throughout the movie. He's chasing the lead in neighborhoods, in traffic, and even in between a crowd of people. It's completely illogical. If you want to watch a better version of this movie go watch Hush.
