Violence is extremely realistic and it's an intense movie; however, I must say I'm getting annoyed with these silent hipster movies that rely on sound effects and bland facial expressions. It was cool at first when Drive did it, but now it's just getting annoying. I get that they're trying to be "deep" and different and all but it just comes across as being lazy IMO. It's a lot easier to have no dialogue and ambient sound effects than it is actually writing an engaging script.
