'Who Are You, Charlie Brown?' is about the life of Peanuts creator, Charles "Sparky" Schulz. Overall its a good documentary, but I feel the animated segments are what holds this film back at times.
I did not know a lot about Charles Schulz going into it, but this movie did a really good job at displaying and explaining Sparky's life and actions. I don't agree with some of the other reviewers here as I think that the documentary parts were pretty good for the most part as it showed how the Peanuts were impactful in so many different peoples lives and how they interpreted the characters. My only complaint for the interviews was that they seemed short and lacking passion at times.
And maybe I'm biased but I found the animated story to be a good idea, but the animation itself seemed very "corporate" and a little out of touch than previous specials even from as recently as the early 2000's.
In conclusion, this is a good but not great documentary. Great for those who have been impacted by Sparky and the Peanuts. Very inclusive and welcoming of all Peanuts fans! If you want to learn a little more about the creator of the Peanuts then give it a watch!
