I feel this episode was OK, but not as shocking, exciting and inspiring as the premiere was.
When father said to his daughter over the phone that he couldn't make it, which let the daughter down, the woman reporter (?) sort of failed to control the whole scene, and ridiculously let the cat out of the bag by saying "It's gonna be amazing."
Also, the mob dance started so suddenly without a reason, which looked strange in my view.
After watching this episode, I realize there's something that may not be fit for flash mob.
It's likely to incur a drop in ratings in January, when the third episode will be aired.
P.S. I didn't expect the ratings that low... Are American families used to watching Modern Family on Thanksgiving Day?
