I found Glass Onion's writing far from “lazy”.
> Instead, he used the most basic and lazy trick in the book: withholding information for no good reason whatsoever … With Glass Onion, our main perspective character was performing. And we didn’t know because the movie refused to let us know.
No, the movie is playing with your expectations around genre-typical knowledge gaps.
In classical murder mysteries like the original Knives Out, our knowledge gap is loosely aligned with the protagonist: they arrive at the scene knowing roughly what we know (“there's been a murder”), they outpace us to see through the unreliable witnesses and extend their knowledge gap through brilliant detective work, until the denouement where they explain what was in plain sight all along.
In Glass Onion the knowledge gaps are numerous and they're sliced, layered and reordered:
- There's a large initial knowledge gap between us and Benoit. He is not just ahead of us: he has a 50% head start. This gap slams shut halfway through the movie by backfilling information on how Benoit really came to receive his invitation to the island.
— A new gap opens: the knowledge we now share with Benoit is not yet known to the guests on the island, and we get to enjoy this with him as a reward for the initial “deceit”. From this point we have caught up with the protagonist, at the small cost of our poor reviewer feeling cheated at having interpreted simple unreliable narration as the movie _refusing_ to present the facts to him in tired chronological order.
— Yet another gap opens because for the first time in the film — only halfway through our murder mystery! — we know who was murdered but we don't yet know who murdered them. This presents us with the classical murder mystery knowledge gap that the reviewer wanted to exist from the film's start.
— The writers pepper extra knowledge gaps that provide more unknowns, some of which are new (who “killed” Miles in his murder mystery game?) and others that exist to provide coherence with the original Knives Out. (Who invited Benoit? Is the murderer of all victims the same person?)
> This gets back to something Hitchock [sic] talked about regarding tension. If you watch a scene where two people talk at a restaurant for five minutes then a bomb goes off, it’s boring for 5 minutes and shocking for an instant. If you watch a scene where someone plants a bomb under a table, then two characters show up and talk for five minutes, you’re wondering the entire time if the bomb will go off. It makes the conversation much more dynamic.
Glass Onion achieves far more dynamism than this! The murder-mystery format itself provides the “bomb under the table”: we start from the first minute knowing that a murder will be committed. When halfway through that “bomb” has not gone off yet the dynamic tension is unbearable. It's released with the first bomb's detonation (someone is murdered), only to be replaced immediately by more fizzing fuses (we learn that another is dead, and that the murderer must know there's an imposter).
