I don't think anyone was suggesting making everything weird.Painting something a different colour doesn't make it interesting. If everything is weird in your game the players will take weird for granted, and it just becomes the new normal.
Without a baseline of normality, weird does not exist.
As has been said, a lot of Phandalin is very generic. Taking one or two elements there and making them more interesting can make the setting more memorable and give the place more personality.
In my home campaign (not Forgotten Realms), I had a generic village the players had to protect from a threat connected to an ongoing quest they were on be the birthplace of the man who had invented the printing press, along with a big statue in his name and a lot of regional pride. Suddenly, Bootblack wasn't just a village like any other -- it had a place in the world that everyone could immediately grasp.
