For me it's just how he writes some of his characters. In Voices, the characters were just bland to me and I couldn't really connect with them. I feel the same way about Garden of Words. But then you have Your Name and 5cm to where you could emotionally connect with those characters. That and the actually stories for some of his films is where the inconsistencies were for me. Like I said, I agree his films do have similar beats, but the quality of the writing is inconsistent from movie to movie for me.
