!! The film:

* TooBleakStoppedCaring: [[spoiler:The four main characters are revealed to be sadistic internet trolls who taunted a young girl online into committing suicide. Meanwhile Alligator, the main antagonist of the movie, who is also the father of the girl who committed suicide, gets revenge on them by tricking them into taking part in a twisted game of survival on an airplane, unfortunately it's hard to root for him either, since he goes as far as to murder the protagonists' relatives, even though they had nothing to do with his daughter's death. In the end, there isn't anybody to root for, and you will find yourself not caring about how the movie gets resolved.]]
* UnintentionallyUnsympathetic: [[spoiler:We're clearly supposed to root for Alligator, who is intended to be the film's HeroAntagonist, since the four passengers he is holding hostage and forcing to play a suicide game pushed his daughter to suicide. Unfortunately, he loses sympathy when he decides to brutally kill the four passengers' family members, who were all innocent.]]
