The moral of the story is deep down inside every interesting and unique individual is an emotionally damaged person who just wants to wear normal clothes when they are "fixed", I'm looking at you The Breakfast Club, The Faculty, This Must Be The Place...
Could've been a better film, if there had have been more ambiguity and less fixing of creative people to make them normal. Seriously I was bummed when the lead girl turned up without her bunny ears.
Cool creature design seemed relatively pointless, because it was an emotional drama rather than a monster film. Also they didn't blend the CG and live action well enough for it to seem realistic or fluid. All in all kind of a waste of time, even if it was an interesting monster to pick. Too much indie, not enough everything else.
For a better emotional drama with literal monsters expressing figurative problems, choose the far better Colossal.
