While there are a couple of adequate aspects to the film, such as the reasonable lighting, basically competent camera work, it's a fundamentally difficult to watch movie, both in terms of the story telling which is laboured, and quite frankly the premise of the film, as pointed out in many of the negative reviews here.
The characters are unlikeable, while at the same time being one-dimensional, existing only to serve as an unsubtle representation of what the writers feel are positive characteristics - which can be summarised as being of non-European ancestry, muslim, homosexual, or politically left wing.
The counterpoint to this is a depiction of those who do not share those characteristics as being evil, to the point of being comical. Think a depiction of Germans in a 1950s movie about World War 2, in terms of subtlety.
Dialogue is uninspiring. And often unpleasant, with scene after scene of foul-mouthed diatribes by primary characters, who seek to project those ideas onto the chosen bad guys - while actually demonstrating their own internalised hatred of 'others' outside their group.
And this is where the film becomes more of a political lecture, instructing the audience that there are good people, and then there are bad people - who are white, heterosexual, and Christian. With such heavy-handedness the film manages to score an own-goal, by being the intolerance it allegedly aimed to reject.
How you treat this film will depend on your political viewpoint, for example if you are left wing, then this will serve to reinforce your world view that white, straight men are evil. If you are politically right wing, you will shake your head at the misrepresentation of reality. Everyone in between will simply switch off after 15 minutes.
