This post was really interesting! I've honestly never watched any of the musicals you talked about (my only exposure to Disney live-action musicals Lemonade Mouth and Cheetah Girls), and I can't say that I'll ever try to hunt them down and watch them. Yin says she watched The Descendants but kind of regrets it...but maybe I can convince her to try 2 and 3 since you're saying they're better, lol! XD
