I loved that each song brought up different attitudes and opinions. And I loved that there was no judgement of those attitudes and opinions. And that it all came around to the hope that we can coexist.
What I didn't like
And I thought that each singer/performer had their own strengths. Each one had at least one song where they took the lead and brought the audience into the song.
My overall impression
I was initially skeptical when I heard that it was about bumperstickers. But that changed when I realized that in order for me to put a bumpersticker on one of my cars (which I have not done in years), I had to believe pretty strongly in what the sticker said. So Kudos for the writing.
