* AlternateCharacterInterpretation: Some have theorized that Donald is actually just Charlie's alternate personality.
* BrokenBase: The film's third act was incredibly polarizing among both audiences and film critics. While some people say that it thematically makes sense and was the perfect way to conclude it, others said it has so little to do with the rest of the film that it drags the excellent first two acts down.
* HilariousInHindsight:
** The "Technology.... versus horse" subtext Donald places in his script makes the climactic battle in ''Film/{{Avatar}}'' so much funnier, as this is pretty much ''exactly'' the subtext Creator/JamesCameron was going for.
** Additionally, the Christian-themed horror film entitled ''Film/{{Thr3e}}'', which has the [[TheKillerInMe exact plot twist]] that Donald uses. ''Film/{{Identity}}'' was also close enough that you could be forgiven for wondering if they hired Donald to write it.
* TearJerker:
** [[spoiler: Donald's death, especially the tragic way Charlie sings to him to try to keep him awake.]]
** John Laroche's entire life [[spoiler: and death.]]
* TheWoobie: John Laroche loses his mother, uncle, [[ArsonMurderAndJaywalking and front teeth]] in a car accident that also puts his wife in a coma, which she wakes from only to immediately divorce him. His remaining possessions are then lost in a hurricane. [[spoiler: Then he's killed by alligators.]]
