Glass Onion follows up after the Knives Out movie, but is nowhere near as good. And a quick scan of the reviews show this seems to be a consensus.

The first 'Knives Out' movie was a surprise hit and seems to have revived the murder mystery genre. I was eagerly awaiting this sequel as I greatly enjoyed the first movie. Unfortunately Glass Onion is totally over the top and (as others have noted), borders on parody with too much emphasis on comedy and not enough on mystery. The budget was obviously significantly increased and has been blown on endless huge CGI set pieces and sets / locations. The slightly spooky and atmospheric manor house setting of the first movie is now a billionaires Mediterranean island.

As for the cast and characters it's fun and must have been a gas for the actors as no one is holding back, but it comes across as hammy to the audience. The ending is also a disappointment so don't expect to be blown away with this one.

Also worth a note is the fact this movie acknowledges the covid pandemic. This really time-stamps the film and it already (kind of needlessly), feels dated to that moment.

Not bad, but watch the first film instead if given the choice 6/10.
