Michael Stearns’s review published on Letterboxd:
Glass Onion is an enjoyable watch with a predictable mystery at its core, but its sometimes sharp dialogue and fantastic set pieces allow it to stand out among the many other whodunit mysteries I've seen. The film has its issues, like its inability to make an actually funny joke and its strange need to inject Covid into its plot and not make any commentary on it or let it really effect the plot in any way, but these things don't make the overall experience all that less enjoyable. I think the main issue I had with it was the way it was paced. For some reason, there's a 40 minute flashback to the perspective of another character midway through the movie that whisks us back to the beginning of the film and slowly trudges its way back to where we left off before the flashback began. To say this was tedious is an understatement. The information in the flashback is important, but it's far from concise and makes the identity of the murderer that much more obvious.
Even though this is a massive weight on this film, I still found myself intrigued by the central plot and the dynamic between the film's stacked cast of characters. I think everyone here, except maybe Kate Hudson, is written and performed very well and it's the dynamic amongst the entire cast that makes this movie enjoyable, even if I didn't really get a laugh from any of the jokes. There's also a few incredible big budget set pieces that are stunning both in the way they are shot and the grandeur of the sequence (specifically the one when the lights go out that expertly builds the tension). The entertainment factor is there on this one, but I can't help but think it stands in the shadow of the original Knives Out.
