There are so many Vlogs on YouTube and most of them are not that great, but the Barbie people have taken a popular but often less than captivating video format and made it into something that works very well for their brand. The writing and animation is entertaining and may even be better than a good many Vlogs featuring real people.
This video shows the importance of knowing your audience and writing for them. In this case writing also includes the feel of the character and possibly the mood of the animation.

A lot can be done with animation. I am working on a scrip for an animation video that I hope to produce in the near future.
