Who knew some random Netflix movie from a first time director would end up being one of the best action movies in the last few years? I didn't. The best thing about this movie, without a doubt, are its action scenes. The action scenes in this movie are brutal, exhilarating, and tense. The fight choreography is off the charts, and the action is clearly presented in all its glory. This movie also has a surprising amount of heart. It's not a masterpiece of cinema, but Chris Hemsworth gives a great performance and the ending is genuinely effective on an emotional level. Great movie!
