I didn't see anything that pinged as sexist. And there's a really excellent argument to be made that Elsa's entire arc is about Elsa vs the patriarchy, and Hans is a very good example of same. I like it as a feminist as well as as a Disney fan. Except for a couple niggling little details like where are the people of color. I vividly recall hearing that the set-the-scene music at the start is Saami music but there's not one Saami in the film, nor more than one or maybe two briefly glimpsed and silent dignitaries of color.
