I actually really liked the video! I think it really helped sell the story and drama of the app. I know that a lot of videos focus on the features of a particular app, but I think this video did a pretty good job of selling the benefits of the app - all while being consistent with the different branding elements.

A video doesn't have to be a features list. It has to tell a story.

(And it doesn't hurt that I really do like The Piano Guys!)
