The documentary Babies is something else. In the best way possible. It's not often you can see something without any narrative or dialogue, yet still be completely fascinated and entertained.
You get a peek at the growing up of four babies from different parts of the world and get to see both the differences as well as what they have in common.
And if you do secretly want to hear someone talk about it, you can see the interviews with the parents in the extras of the dvd.
