The original LoZ was also 30 years ago. We can't pretend like the series didn't gain tons of new fans since then. It's had like 10 masterpieces since the first game. The game that set the formula that BotW completely changed is still the highest rated game of all time. It was extremely bold to change that.
Not to mention, the things BotW changed that cause controversy aren't things that it has in common with the original LoZ. The only thing that causes people to make the original LoZ comparison is more focus on exploration. No big dungeons, no item progression, breakable weapons are all completely new to Zelda.
I don't think anyone is denying what Breath of the Wild did was extremely bold, but it was an evolution of the franchise deeply. God of War is practically a new genre of game compared to the previous titles.
