The trailer made more sense than the goddamn movie!
It´s weird, it´s not like they are lying to us, but if you watch the trailer for High Rise, they sell it as a "normal" movie with 3 acts, and we expect that the details will be in the movie. But no, there´s the plot, the characters and images but not solid storytelling.
I Liked the movie, but the movie the trailer promissed looked better :)
