Making the comparison with the title (Glass Onion) I can say that the movie also ends up having many layers like an onion. Several completely unexpected twists and turns that catch us unnoticed and that give the movie a great unfolding of the action.

It's a mix of a slightly tense atmosphere (normal and intended in a mystery) and also excellent episodes of pure, clever comedy. The sequences are well done and allow the audience to think or laugh shamelessly at the characteristics or actions of some of the more eccentric characters (a theme visible several times during the film).

Note that the ending, at least for me, leaves a little to be desired, perhaps because it is a bit exaggerated, needless, the reason is understood, but even so it could have been done in a better way.

To conclude, the cast and the unexpected participation of some very well-known actors and figures raise the bar for this mystery. Great individual and collective performances. Good entertainment A solid and very well made film. I recommend it of course :)
