Glass Onion isn't a sequel to Knives Out so you could just watch this one without having to watch the first Knives Out. That said the first one was just a little bit better though. But I enjoyed this murder mystery as well. In this whodunit they cleverly accentuate some scenes to put you on the wrong path. You watch out for clues but in the end it's still a surprising outcome. The best thing about Glass Onion was the acting. With a cast like that it's obvious the acting will be good and it was. Good cinematography as well, they clearly had a big budget for this movie. For the fans of murder mysteries.
