I'm still waiting!

I was waiting for some big epiphany on the meaning of life!!! Kind of a pointless movie but still enjoyable. I didn't like the character sara. She was rude to her doting father. She would never answer when asked a question, she would just stare with this dumb look on her face( though I would still totally do her! lol).
This may be a spoiler, but my guess is that the answer was that there is no reason for why things happen and people do bad things just because they can. Free will and dumb luck.
