There’s no question mark in the title of “Where’d You Go, Bernadette” (2019) and yet it’s asking us all something very important. What’s the difference between eccentric and crazy? The answer is a little too pat – the eccentric must be productively creative to keep from becoming menacingly crazy – and awkwardly told. We’re dealing with a rather serious issue and yet there’s a lot of uncomfortably wacky hijinks pitting protagonist Cate Blanchett against neighborhood ubermom Kristin Wiig. And some of the dialogue is a little over-the-top, even for a crazy person. And there’s an I-can’t-quite-place-it unlikability about Blanchett’s husband, Billy Crudup.
