This title is considered as a stylized title as per our capitalization rule. I quote : "One exception is officially stylized titles. The first letter of the film mother! and the television series black-ish and grown-ish is not capitalized. Another example is Japanese titles in all caps such as the film GHOST IN THE SHELL and the series DEATH NOTE. In all cases, the stylized capitalization is used in the opening credits, on the official website and in press material such as press releases. "
