I should really sleep on it, but I just walked out of the cinema and need to offer my ramblings in an effort to determine whether I liked or loathed what I just saw..
The point of the film was to have no point. It was true to the ideology of the joker. Chaos, madness, meaningless. It wanted to be ugly, grim and have the audience feel confused. There was never a redeeming moment, but a steady descent into bland soulessness. For the fact that the director deliberately put together this film to irk the viewer and leave them feeling black and depleted, I gave it more than 1 star. The music and the presence of lady gaga or whatever his name is added nothing. The music was bland and tiresome, again achieving is purpose to be the polar opposite of what a movie should be. The repeated lyric, "this is entertainment" an irony to slap the poor viewer in the face who paid his ticket and gave his time to see this anti entertainment. It's like the pyschopathic personality of the joker wrote the film and was so grim that he even betrays himself, essentially making it a non event. It tries to be a artpiece rather than a movie. Be prepared, lower your expectations.
I sat through it.. Just. It was horrible, but because I think deliberately so, I give it a 2. It's like staring at a pollock painting for 2 hours. It's a mess, it doesn't change, it isn't pretty and it has no meaning. And then it ends.
After sleeping on it, I think this film has played out in my mind and is quite memorable. It's a tragedy.
