Thanks to the Roman numeral helpfully attached to its title, audiences should have a fair idea of what to expect from Disney's latest animated musical: It's Frozen, but ya know … twice! Twice the peril! Twice the naïveté from sentient snowman Olaf! Twice the number of screamy power ballads for Idina Menzel to perform at the Oscars! But for all of its considerable pleasures, Frozen II is also more often Frozen Too – as in too formulaic, too unnecessary, and, for its target kiddie crowd and at least one grown-up, perhaps too confusing.
