I enjoyed every minute of this film. I'm just a little older than these guys and love all of their music. Although I'm a blues/jazz fan and wasn't much into mainstream or top 40 music growing up, I always liked what the Beastie Boys did. Fact - I have all of their music converted to reel to reel because I prefer the warmer unmolested sound.
The film kind of left me with a tear in my eyes - Mike and Adam did a great job conveying the relationship they all had and you clearly can feel their pain at the loss of Yauch - as many of us fans have but not in the way these two did.
The film is a great watch and one all fans of music need to have in their collection.
