I went with some friends to see Frozen II last night. Despite a good dose of the usual Disney formula, it was actually quite entertaining, and really hilarious in a few spots.
On a music note, there were no big hit songs I heard that will be repeated ad nauseum like you had in the first movie. Also Idina Menzel had far less belting going on, which was a huge relief.
According to one article I read, in Frozen II, Elsa comes out as being both gay, AND a Trans-Exclusive Radical Feminist.
