I had ambiguous feelings about this movie when I first saw the trailer. On the heels of Heath Ledger's truly incredible portrayal of the Joker, I found myself watching the trailer and asking myself: "Do we actually need another incarnation of the Joker?" And my initial answer was "No, we don't."
However, as I watched the movie, I found myself completely caught up in the story of Arthur Fleck. Phoenix's performance was truly riveting and was so believable that my wife and I both left the theater in complete silence. We both needed to process what we'd just seen, and it took a solid ten minutes before we could dive in to a discussion of the movie.
I've seen critics condemning this movie as a "handbook for incels" and saying that it will incite violence. But neither my wife nor I saw anything of the sort. What we saw was a story about how someone with mental illness can be forgotten by society and the devastating effects that can have. We both felt empathy for Arthur's suffering, and we both found ourselves pulling for him to get better, for his circumstances to change for the better. His initially gradual and then quite sudden plunge in to chaos was inherently bad, and the film portrays it as such. You find yourself saying "No, Arthur! No!" as he chooses to embrace the chaos and violence that has been simmering beneath the surface for so long.
All in all, a truly incredible film and arguably one of the best incarnations of the Joker that has ever been. Well done, Joaquin Phoenix, well done, Todd Philips.
