It's probably the best acting Chris Rock has done that I can remember but it's still Chris Rock acting so it's still not good. Rock was good in select scenes but he can't do the heavy lifting the part requires and he can't slip into a character. At best it's Chris Rock saying the lines somewhat convincingly, at worst it is Chris Rock saying the lines badly. He can't do the Sandler thing where he can, when he chooses to, convince you he's someone else other than who he is.

You're right, Bug Eyed-talian is very much intentional. It's just a horrible choice and a horrible performance. Like comically, distractingly bad.

Schwartzman acquits himself better than both but that monologue in the jail was awful as written and as performed. He might as well have started it with "Gather around everyone, I will now walk you through the central theme of this season in the most on the nose way possible"

A better actor could have made it seem less like he was reading a book report and created some tension in that scene.
