First time I've seen this, I was kind of drunk and distracted. Because of this, I picked up some pieces but didn't totally get a full grasp of the film.
Four years later, I rewatched it and, well, it's not as exciting ang thrilling because I already knew the plot twist. However, I did somewhat enjoy the humor that is the stupidity of the characters.
Thinking about it, the plot is actually pretty cool and complex. The implementation such as the acting, background music, camerawork, etc. are a let down, however. Maybe if I've seen this sober for the first time, maybe I'd appreciate it much more.
