I just dont get the whole knife thing. I mean people still have to like cut food and stuff like that, right? I don't think average people are using mini lightsabers to cut up their Life Day dinner. As for boats, we basically see a boat in TPM. It's essentially a submarine but close enough.
As for Disney not spending money, I just don't think thats fair. The budgets for the movies I think have all been more than adequate. For tv shows Id expect the budgets to be smaller.
