The first 20 minutes of 2 AM made me dread the rest of the film. I feared this would be another one of those low-budget features in which a bunch of twentysomethings sit around (in a bar, this time) and talk about their lives and their relationships and how they just want to find their place in life. In addition, the acting in those first scenes was uneven, one character was extremely unlikeable, and I felt restless.
Fortunately, after those rough 20 minutes, 2 AM blossomed into an absorbing drama, the acting grew more realistic and consistent, and I enjoyed the film very much. Most low-budget "relationship" films I've seen lately have focused on insecure white guys; 2 AM portrays a broader spectrum of characters and points of view.
