End Of Watch is more about the characters and their day to day activities than most cop movies. It's definitely a great movie and yeah, I'd recommend it. I liked it more than Training Day (same director) which I kinda think gets a bit overrated. There were a couple parts were I wasn't sure about the hand held camera effect but for the most part it was really well done.
I'd recommend Rust And Bone too if you dig foreign movies. Probably the most accessible of the foreign movies I've seen this year. Kinda melodramatic but it's really powerful stuff tbh.
I'd only recommend Looper to someone who's a big sci-fi fan. For all this talk of how original it was, it steals so much stuff from other sci-fi movies. Safety Not Guaranteed is a better sci-fi movie
