Usually, when people are completing a menial task, I'll sarcastically note "He/She are doing God's work". While I'm not an American who grew up watching Fred Rogers, I can safely say, without a hint of irony, he was doing that very thing. God's work. Roger's simple goal to spread the message of self-worth and identity is more current than ever and has no boundaries with regards to one's age.
I am so glad this documentary was made to illuminate someone I barely knew anything about, but now have a deep respect for.
