A riff on Knife in the water ... though do not compare those two! So no pun intended as always. Polanski has not lost his touch. Whatever one may think of him personally (I won't go into his legal issues, you either know about them, can look for them and/or do not care) ... he is a really good director! The cast he assembled speaks for itself.
The comedy is something you have to like, but the Hotel Manager is absolutely fantastic! Then you have John Cleese who is able to perform ... in many ways! Even without text ... as his comedy tour says (title): watch me before I die - I am paraphrasing here ... but you get the point.
That said, there is a lot of mayhem going on ... and it all has the absolute highlight at the end ... cgi "joke" ... but that should not matter ... had a few laugh out loud moments myself ... you can have quite a lot of fun with it.
