It's entirely possible that sending the audience out feeling lousy was intentional

The story-telling is good with flashbacks.The film is both funny and heartbreaking. You smile in a scene and get a soulcrushing revelation in the next.

Ok... Let's be honest. It cannot be the best movie but is quite enjoyable. The movie has the potential to develop a great plot for future movies

The film never slows down or bores, plunging from one harrowing sequence to the next.
