It’s in that movie but it’s not from it. Did you seriously think it had never been said before that? It’s been used for centuries in different forms, even exactly as said in glass onion.

Same with “it’s so bad it’s good” both with and without “nah, it’s just bad” after. I think one of the most well known things like that is “The Room”, and many reference that movie when something else fits the description but it’s not at all from that movie, it existed long before it.

Janelle Monae crushes it in her role. I mean absolutely crushes it. In it she is acting in the role of a character acting in a role, which is actually really hard to do in a really satisfying way, and she absolutely pulls it off. What’s more is that she lets the veil slip just enough, as an actress, for the character playing the role to be believable as an actress. Like her music and visual artistry as an R&B performer is incredible, but there’s still a part of me that feels like the world lost something from her not going into acting. But if she had, she’d probably have put out an album that would make me lament she hadn’t focused on R&B.

Nah, I thought that quote from the film summarized it quite well…

Yes, he was intended to be a fictional stand-in for the muskrat.
