You cant escape Disneys phenomenon Frozen.It is the highest-grossing animated film of all time and one of Disneys top franchises. It was the most downloaded movie from Apple in 2014, and kids everywhere are still singing the movies anthem, Let It Go.Heck, its now probably stuck in your own head right now, even if youve never seen the film.So why has the 2013 movie stuck around for so long for the under-5 set?Experts say it is not just because you can find images of the movies sisters on everything. Elsa and Anna are on dresses, on scooters and even on jelly beans.The news that a long-awaited sequel is finally coming in November 2019 was met with cheers (and a few groans) across the Internet.
