From the very beginning, it’s clear that “Beau” is facing considerable challenges in life. We then jump ahead forty years to find him living a nearly isolated existence within a chaotic city where constant sirens and noise disrupt his sleep. It’s following one particularly noisy night that he abruptly realizes he needs to get to the airport to visit his affluent mother. Predictably, circumstances intervene, preventing him from making the trip... He attempts to contact her, but instead reaches the delivery person who is standing over a body—decapitated. His mother? Now he’s compelled to embark on a journey – without access to his credit card – in order to attend her funeral. What follows are several mildly amusing, though mostly overly strange sequences that blend fantasy and invented elements during his travels. Joaquin Phoenix delivers a noteworthy performance as the kind but frequently bewildered “Beau.” He commits completely to the role, successfully eliciting both annoyance and empathy from the audience as the story moves—unevenly—toward its final moments. Nathan Lane also contributes effectively, albeit in an exaggerated manner, portraying surgeon "Roger," while Patti LuPone (as his mother, "Mona") is revealed in a surprisingly unusual way later on. The writing occasionally has some cleverness, but for me, the film’s length and episodic nature are simply excessive. It feels as if Ari Aster had gathered numerous concepts for his character that he then attempted to combine, similar to “Forrest Gump,” with the expectation that the final result would be enjoyable. I don't really care for things being so far-fetched. It doesn’t necessarily require a conventional beginning, middle, and end, but I do prefer a narrative to be grounded in something a little more realistic than this is. I am pleased that I experienced it on the big screen, but I can confidently say I won't revisit it.
