Saw it last night. My kids will probably enjoy it but it's not memorable. Songs aren't great, dialogue is flat, Anna is intentionally obtuse (her iq is potato when talking to christoff, trying to recreate / revive the comedic scenes from the first movie), whole lotta crap retconned in, artifacts and stories from their parents that didn't exist at all in one added now to take the political route (and to sell merch with new dresses and accessories which is a given with kids programming, regardless of plot).
It's disappointing because they've had years to develop this and this is the plot they came up with. I've had great talks with my girls about Hans and Elsa and Anna after the first movie, even though they were 2 and 4 at the time. This one is more convoluted and less concrete in terms of real world application. The script felt like they were just saying lines to move the story along. Take the next right step sounds like a good moral lesson until you realize that Anna is willing to destroy people's lives and livelihoods to do it, as if that will restore some sort of balance to the scales of justice instead of impoverish a different group of people. They had an opportunity to establish clear thinking and problem solving to bring justice but chose the Burkean baseball bat instead, with magic swooping in to save the day. Why didn't the spirits allow a slow dismantling and water level management that doesn't sacrifice one party at the expense of the other? Who knows? These issues are too complex for a kids move to resolve in an entertaining manner to children, thus why they should have been avoided. And then they crowned the psychopath queen. All good leaders stand ready to destroy their kingdom at a moment's notice.
