Crime 101
This was a bit weird. It's very old school, gritty, basic movie, and it's tough to put either a good versus bad.
Director and writer was only 50 years so props to him doing a great job on it. I did not recognized any of his movies so I was a bit shocked how it all works.
There ain't no spoiler but I don't want to ruin it for you. The detective work by Mark Ruffalo was really meh, it's not his fault cause he only had a little bit to work with. However, he did a solid job esp on the end. Halle Berry, played herself and again, due to limitation of a not so developed character development. Then we also got Chris Hemsworth, who plays a bad guy and also very one dimensional. He can't hold a conversation at ALL, and if it wasn't his good looks, he wouldn't be able to date a girl. Hilarious.
Now the good part of this - the premise and the script was decent. You know what's going on and the final part of the movie, you KNOW it's coming. How it ends and wraps up was a bit of a good wrap up. The transformational ending on the last 10 mins was decent. It COULD have ended in so many ways however the director chose to extend it and wrap it out nicely which to me - saved the movie.
TL;DR - old school cop thriller, good wrap up but weak character setup. Chris H can't act for shit but that's cause his character is so dull.
