First off you have to remember it is the same writer as Training Day. Then you have to believe that he must have gone to a joint training camp between the Taliban and Mexican Cartels or something since Training Day to come up with such a tense, unpredictable script. But End of Watch is more than that. It is warm and sweet (yes), and a great showcase of Gyllenhaal and Pena’s talents — which thanks to a documentary-style cinematography, and the actors’ 5-month immersion program with actual LA cops, make for a very authentic, rich, and overall exciting film.
