Bullet Train: Fun Ride, But Did Anyone Else Feel the World-Building Was… Off?

Okay, so I just got out of Bullet Train, and I had a blast. Seriously, Brad Pitt's comedic timing is on point, and the fight choreography was insane. Plus, the whole aesthetic was just dripping with neon-soaked Tokyo vibes, which I'm always a sucker for. But as a sci-fi/fantasy nerd with a world-building obsession, something felt a little…off. Specifically, the whole 'Japanese underworld' thing felt kinda...cartoonish? Like, I know it's stylized, and that's clearly part of the point, but it felt like they were drawing from, like, the imagined Japan from a Yakuza video game rather than anything grounded in reality. The villains especially seemed like they were trying way too hard to be 'cool' and 'intimidating' with all the family stuff and honor codes. Did anyone else get this vibe, or am I just being overly sensitive? And don't get me wrong, I love a good over-the-top villain. But I guess I was hoping for a bit more nuance. I mean, the movie is set on a bullet train in Japan, they could've dug a little deeper and added more depth to the Yakuza clans. Maybe I am expecting too much depth in a movie that is mainly focused on action. What did you guys think of the Elder's backstory? The part where he showed up at the end felt slightly out of place, but was also interesting.
