I feel I half agree with you. The other half of me thinks, there's a lot of things we change for an actor acting a character. After all, it's an actor, playing a character. Someone called Ben can play a guy called John; your grumpiest aunt can play a sweet grandma; often we have actors in their 30s and 40s playing ternagers and 20s; and men playing women even used to be a thing.

I think you have a good point, but I also think it's okay to have an acceptable disconnect of, this is people acting out a story, not the real thing happening in front of me.
