Saw this today....It's so effective in some parts in terms of creative costume design and an atmosphere of dread, chaos, and depravity, the visuals are often gruesome and resonate far more then the rest of the movie.....Unfortunately, the rest of the movie, which takes up 85% of the time ranges from insulting to average, veering from offensive to laughable sentiment in a single frame. I love the continued vocalization and depiction of the struggle of the classes, I do think the movie goes far too close to simply mocking the underclass and glamorizing their butchery at the hands of the 1%. It needs a new writer, and someone to guide the franchise back to the kind of lower key horror and terror that the 2nd was so effective in creating. This whole new shift into Hunger Games territory is stripping the franchise of what made it an intriguing and innovative concept in the first place.
I also want to say the movie creates almost a war between races, of which the whites are shows to be the losers, yet the films own writing, and direction speak to a more subversive battle being clearly lost. I loved that actor in Justified, and as an actor he shines here, but he is forced to spit out line after line of ugly, demeaning racial cliches.....This movie emits a lot of whats wring with the industry.
*I just think about p*ssy and waffles (reinforcing a very ugly stereotype, which yes, exists, (as in members of all races who are uninformed, uninterested in politics, progression, etc, and are teh reason why in part things like The Purge and Donald Trump can exist) but is shown here without nuance, and clearly comic relief)
* Don't sneak up on black folks
* There's a bunch of negroes coming, and we sitting here like a box of fried chicken
* My neegro (towards the end)
Those were the ones I remembered clearest, embarrassing, hackneyed lines that reflect a real ugliness in Hollywood. Also, the 'Candy Girl', a potentially troubling character, seemed to be very much at times both badly acted, and trafficking in stereotypes as well.
Also the interplay between Grillo and Dixon was just unneeded, and clearly setting up a harmonious relationship between black and white men of action.
As far as other plot holes and observations:
*Why would they not just kill the four girls coming out of the car.....
*The Mexican characters backstory and persona was also cliched and insulting, on a few levels.
*Frank Grillo's relentless approach to being a badass was a bit much after the first few scenes
* Just walking into the room and pulling guns on everyone
lines. Oh and the black men having to be the sacrifices for a better future
