The District

As Jori mentioned below, The District was also a bit hard for me to see.

The whole setting of the film was in a dirty town, with dirty schemes, with stereotypical characters and with just too much cleavage.
On some scenes, I just wanted to turn my eyes away from the screen because of the scenes' way too vivid portrayal of the society's dirty truth and over-sexualized women, and I wondered, why did the makers of this film have to go this far to point this out?
And then I thought, well, some of these truths are supposed to be uncomfortable and we usually turn our eyes and attention away from it since we do not want to get involved with it, and most of us don't even care to really know it.
We're supposed to be bothered by the film if we are bothered by the society's unpretty reality.

But despite its depiction of the dirty reality, it was fascinating how they chose to use a fantastical element of going back in time with a time machine to show portray this reality. Furthermore, the main character's romance ending because of his crush actually being a lesbian all of a sudden seemed like a perfect ending to show 'there is no such thing as happily ever after.'
I also liked the animation style of the film; it was unique and fresh, and I haven't really seen that kind of style anywhere else.
I wonder what the reaction of this film was like when it was screened!
