I found this trailer while ago (maybe a couple months) and I knew it was going to be one of the best movies I have ever seen. I was right!, I just watched it a couple hours ago and there's no way to describe it, I can only tell you this one is a masterpiece of art, like they would say here, "a major cinema event".... Highly recommended!!!
Note... The paramedic story, the best one!! Check out the trailer
