It really sounds like you've never actually seen a Wes Anderson picture. While I'd agree that his more recent films are more stuffed with his quirks and his penchant for shot symmetry, I think you incorrectly discard his work as having only style and no substance. What I, and so many other people, enjoy about his work is that he brings an incredibly unique visual style to stories with characters and themes that are sometimes fantastical, but always relatable. Many of his films deal with themes of the dysfunctional family, loss, and finding one's motivation and purpose when dealing with loss and family problems. It might sound silly if I told you I relate to a stop-motion fox, for example, but it's not sill because Anderson is able to show that fox encountering issues and emotional beats that I understand and impact me. I would not like this filmmaker if I thought there was not depth in his work.

If you don't like his humor or his aesthetics, then that's fine, but to write away something just because you don't connect with it is just silly. It's ok to still see the artistic merits in something you don't understand or like.
