It's a good show. I don't see a problem with naming kids after characters honestly. If I would, I would mostly do it because it sounds good.
On the other hand, I could also name my children after important people of History, Kings or Queens for example. Which is another matter obviously but yeah, humans always name their children after something they know or people they like, or characters or whatever. No big deal. While I agree "Thomas the Train" would be hilarious, lmao
