I liked it, but i understand why people hate it
Without spoiling too much, what do you think was the movie's main issue? The acting? The plot?
People don't think in allegory. Those that can see what the director was doing see it as pretentious. Others might think on it too much as a political statement and so dismiss it as political. I think mainstream folk walked in expecting a gross-out horror film and got an art film instead.
The movie is visually stunning and worth seeing if you like art house cinema.
