Sorry to resurrect this thread. I watched the new one, Wake Up Dead Man, against my will. It's a more functional mystery than Glass Onion, but still suffers from similar writing problems. Once again, the suspect with the most screentime and the most capability to pull off the murder is the one pulling the strings. It's clear before you even meet the rest of the side characters. What caught me off guard was the willing involvement of auxiliary suspects in the scheme and the villain's motivation, the latter of which Rian cheats to achieve.
The antagonist, Martha, wants to kill a corrupt priest to avoid the sin of greed from infesting her church, as he plans on recovering a secret diamond from a crypt that the church owns, and only they know the location of. The film tries to stage her as sympathetic when uncovered (when she literally chooses to commit suicide over being caught and doesn't even hide the diamond).
Her decisions throughout the plot are nonsensical. Rather than simply kill the priest, frame it as a suicide or accident (the former of which would easily be accepted due to declining attendance and pressure from members), and leave the gem as a secret in the crypt, or stealthily pluck it during the burial, she chooses something far less discreet and safe for those uninvolved.
Instead, Martha involves multiple accomplices in a blatant murder, which she frames on Friar Jud. She uses an idea from a mystery murder novel on the church's set reading list and commits the crime during the middle of a church service, in front of a small crowd of witnesses who have or are set to read that book. She then takes a look-alike of the victim and buries him in the crypt to retrieve the gem, making it appear as though the priest rose from the dead on the security camera.
Not only is it unnecessarily cruel and reckless to pin a murder on an innocent man who then has every reason to find the truth, but this method also requires at least one aide to learn the secret and draws a gratuitous amount of press.
Also, there's plenty of "I have nothing but contempt for your backward beliefs, but Jesus said to be nice somewhere," baked into the script. Right-wing strawmen feature for comedic relief, and there's a clear message of acceptance and kindness through faith, instead of being judgmental. Not that "Forgive your enemies" is a bad message, but the script treats characters like the priest's long-dead mother as a misunderstood victim when she tore up the church and beat a child in a wrathful, greed-induced search for a diamond her husband did not want anyone to have. There is evidence that her spouse hated her for dressing provocatively, but they didn't sell the idea that she was actually abused, nor that she was entitled to the fortune.
Benoit Blanc is also a vitriolic atheist, through and through. Even his "Damascus" moment comes down to him feeling sympathy for Jud, and he immediately follows it up with "God is a fiction." He's not even momentarily agnostic, and the beard and hairstyle really make him feel like Rian's self-insert here.
Wake Up Dead Man displays solid cinematography, serviceable acting, and plenty of good scenes with Jud, but the film, overall, is worth sleeping on.
