I have the complete opposite opinion of you. Have you seen Bottle Rocket? It is his first film and completely lacks the grandiose Anderson visual aesthetic. Still has Anderson dialogue.

He is mainstream and accessible, yet has a quirky style with obnoxious framing, grandios dialogue, and 'fun' color palettes. Because of these quirks, the gen public lauds him and acts like he is an arthouse director or someone totally weeeird. In my lower level cinema class, 90% of the class listed Wes Anderson as one of their favorite directors, usually next to Tarantino.

Compared to mainstream cinema he is weird. Tarantino's quirk is his storytelling format. Anderson's is his visual style which personally I appreciate as totally unrealistic. Movies have a burden of being 1:1 representations of reality, what you through the lens is, excluding cgi, an accurate representation of reality. Wes Anderson deliberately break this through his visual style. They are meant to be a false, idealized reality. For example in The Grand Budapest Agatha is described as having a birthmark that looks like Mexico and in the movie it is literally in the shape of Mexico. Everything in TGB is exaggerated because it is based on storytelling of Zero, not reality.

I think he is one of the best directors out there because 1. Obviously. I like his movies and find them enjoyable on every successive viewing. 2. He has a unique visual style that he has mastered. 3. His dialogue is different and interesting. When Suzy asks Sam if Snoopy was a good dog and Sam says "Who's to say?" Man that just connected with me I love it. 4. He writes original screenplays which I appreciate.

I feel like I'm just rambling and I dont think there is anything that will change your mind. If you don't like the style of his movies you will hate them because they are drenched in his aesthetic. I also think that just because his style is bold and in your face doesnt make it bad, just polarizing.
