Being Elmo is about the puppeteer of Elmo, Kevin Clash. I would highly recommend it to anyone who grew up liking Sesame Street. The movie talks about Kevin when he started making puppets as a kid and doing shows in high school. How he got his first break on TV and ultimately reached his dream of working with Jim Henson. One fact that I found interesting is Elmo was someone else's puppet first and he got tired of him because he couldn't find his niche. After he had enough he tossed Kevin the Elmo puppet and told to see if he could do something with him. Kevin then turned Elmo into one of the most beloved puppets on Sesame Street.
If you got some spare time and you are looking for something interesting to watch with the family I would say give this a watch.
