Yeah, I don't care for it either. I'm not really keen on playing down the fact that this is a guy from the 1940s who's suddenly in the modern world; he doesn't have to assimilate or like everything that happens. Explore that rather than paper it over and just use it for jokes. It's okay if he has a 1940s haircut and doesn't wear blue jeans and listens to Frank Sinatra and is having trouble adjusting to the way everybody acts now. He grew up in a very different time; he doesn't need to suddenly be all, "Guys, my haircut is all old-fashioned! I need to look cool and get a smartphone!"
