I admit that I am as prejudiced as one could be, so take my 10/10 with a grain of salt. I love Ireland, I love Dublin, I love U2 and I like David Letterman. So watching this film, seeing places I know and love with U2 talking about their music and others talking about U2 it was unavoidable that I watch this, unavoidable that a few tears came to my eyes and unavoidable that I like this film. If you do not know Ireland but are a U2 fan you should enjoy this film as well, but you will not understand a few of the connections. And, if you have never experienced real pub life and music in Ireland, I beg you to do so as soon as possible. Then watch this film. It's not just about U2. Sláinte.
