Why do I see such negative reception for Aetherdrift?

I am an extremely new player, I don’t even have my own deck yet and have only played 1 game total, but plan on getting a commander deck in the near future. I looked at upcoming releases and the aesthetic / art style of Aetherdrift seems so cool to me. Someone mentioned in my local gaming store people aren’t as excited about this “release” (is that the right word?) I have also seen several negative comments on it online. What is it people don’t like about it?
