Can anyone explain what is funny in this movie

Rating: 2/10 (21 June 2020)

This movie is not funny at all. It just failed to deliver a comedy. It is sort of watchable, but it is essentially boring. It happens from time to tome that a highly praised movies I do not find interesting, but I do understand when why they are praised. This one... I have not a clue.
The story is flat, the attempt to twist things totally not interesting and overall superfluous as paradoxical as it sounds. This comedy is supposed to be kind of intellectual one, as it is not slapstick, so there has to be something else. I see nothing. You can watch it as some sort of expensive production of a TV episode of something, just for its cast but I fail to understand what all these high class actors are doing. Supporting what? Story, scenery, accents...? You could put there any group of average actors and the movie would have had the same quality.
But these days, the quality of entertainment got so low, so, yes, from that perspective this is a super movie. I am sure it will be very soon forgotten.
And I am very certain that people went to see this movie attracted by the cast thinking the same as me that a movie cannot be nothing if it gathers so many stars. Sorry, it still is nothing. At least as a comedy, it is an attempt, a very expensive high-school exercise with all fancy scenery, camera and all that, and yet nothing funny. Not a single thing.
