Well, unlike No Time to Die, it at least didn't introduce a new character who had a fraction of the protagonist's muscle mass and almost no prior fighting experience, but who proved themselves to be as badass as the hero through sheer gumption and cheerfulness. (Ana de Armas' Paloma exited that movie quickly enough for it to more or less recover its dignity, but, yikes.)
I'll absolutely give you the muscle mass but I think it's clear that the three week's training line is a lie/joke.
Interesting correlation though. Paloma was by all accounts a dull, one note character before one Phoebe Waller-Bridge got her hands on the script and helped her become one of the highlights of the film (YMMV obviously)
