I got to see it when it premiered at The Museum of TV and Radio. I thought it was very well put together and very moving. It's true that it's not like "Of Muppets and Men", there isn't much about the puppets or puppeteers we know about (though are a few shots of them training new puppeteers).
However, I believe the documentary is worth seeing anyway. You learn so much about the different countries and what their difficulties are, and how they're desperately hoping Sesame Street will be able to help them. It really represents the potential a show like Sesame Street can have. If it's going to survive, it needs to spread its message of communication and peace. It might be too late for the parents, but perhaps we can reach the kids now. The show brings out so many emotions, sometimes the audience laughed for 5 minutes, other times they cried.
For me, the best scene is when the puppeteers from Bangladesh receive their puppets for the very first time. You can tell they're so excited and happy. You can imagine that it must have been the same way for the American puppeteers back in the day. At the Museum, the film's editor was there and she said that was the first scene she chose to work on.
On a slightly more cynical note, I felt the documentary also demonstrated how naive and complacent we are in the U.S. We really don't understand that other countries don't have the luxuries we take for granted every day. Some of these countries have been at war for years and we don't realize how deep the resentment and fear and bitterness is. And sometimes it comes out in the documentary just how clueless we can be, even when we're trying to help. At least that's what I noticed, lol.
