The new characters are all horrible people. Unlike the prequel you have no character to root for from the very beginning.

The references to COVID and social media like TikTok, Twitch and Instagram made me cringe.

Everything that happens off-screen. In a nutshell this a mystery by omission and only works because half the things the protagonist does happen off-screen. Only for it to hit you with a sudden 'Ah-ha! What you didn't know is that between each scene something else happened that we didn't show you.' This is the laziest and worst storytelling in a mystery I ever saw.

I heard Rian Johnson's friend said that it feels like he wrote the script >this< afternoon. Referring that the story is more relevant than ever. But to me it felt like Johnson wrote the whole script in a single afternoon on a napkin.
