I thought the movie was quite good. It was an interesting take on the monster movie genre.
The overall theme of the movie seemed to be about privilege and oppression and how these concepts relate to today's society. Each of the main characters represented a different demographic that is largely oppressed in some way, in our current society. Among the oppressed were a person of color, a person with a disability, and a gay man.
The monster himself symbolically represented the societal oppression that all of these individuals face in our actual society. This was portrayed by the film's antagonist's anger being directed towards the monster.
Not surprisingly, the villain in this case was a heterosexual, white male who in our North American society tends to be the most privileged.
It was an interesting and well put together movie that clearly had a relevant social justice message for society.
