- Alternate Character Interpretation:
- Gavin: Courageous atheist hero? Or Manipulative Bastard with a severe case of White Knight Syndrome?
- Joe: Crazy, fanatically religious and domineering husband? Or a borderline mentally unstable person that found solace in religion and was having a happy and productive life until he was pushed over the edge by Gavin's actions?
- Shana: A vulnerable woman who was tempted to cheat by Gavin's manipulating? Or a selfish bitch who just uses men to get whatever she wants? Add in her previous troubles with prostitution and drug addictions and it becomes even messier.
- Hollis: Was his decision to forgive his wife for cheating on him and accepting the fact that he's not the biological father of his kids a brave thing to do, or a copout that makes him an Extreme Doormat?
- To be fair, Hollis' wife denies to ever have been unfaithful to him, it is hinted that artificial insemination was used with Hollis' brother acting as the sperm donor, all because Hollis' wife wanted to give him a family. On the other hand, he discovered his sterility because he was failing to have a child with his mistress, maybe it was a case of Laser-Guided Karma?
- Designated Hero: Gavin comes across as this. Deliberately seducing a married woman to have an affair with him is a dick move by itself, but he also admits that he manipulated Shana in order to make her fall for him. Not to mention the fact that Joe and Shana were shown to be pretty happy together, and the reason Gavin decided to seduce Shana was because he wanted to get back at Joe for being condescending towards him and his gay roommate and to "save" Shana from an "oppressive" life.
- Designated Villain: Joe. See Unintetionally Sympathetic below.
- Esoteric Happy Ending: Word of God says the ending is intended to be a Bittersweet Ending, as Hollis reconciles with his family and the fact that he is not the biological father of his children, and Shana has now Outgrown Such Silly Superstitions of religion, but... she is now emotionally broken, with her marriage demolished, her husband in prison, her lover Gavin dead and all alone. It will be a damn miracle if she doesn't relapse to her previous lifestyle.
- Stop Being Stereotypical: More than a few viewers, atheist and religious, took issue with the film's portrayal of the two main male characters. Gavin is an atheist, and his manipulative actions rubbed off wrong on several atheist viewers who felt he furthered the stereotype of atheists as hating religious people just for being religious and for being a selfish Designated Hero. Meanwhile, Joe, being Unintentionally Sympathetic notwithstanding, is disliked for furthering the perception of Christians as condescending towards atheists and being fanatics.
- Trapped by Mountain Lions: Hollis' subplot bears absolutely no weight to the Shana/Gavin/Joe love triangle, other than distracting Hollis.
- Unintentionally Sympathetic: Joe. His reaction when he confirms that Shana is having an affair shows him to be truly devastated and heartbroken.
- What an Idiot: Gavin accepting Joe's invitation to debate atheism vs. Christianity. This will surely end well...
- To an extent, Gavin initiating the affair with Shana. It would likely be discovered one way or another, and surely he had to at least have known that if Joe discovered it, the consequences would not have been pretty.
