As a die-hard Gorillaz fan I found the movie to be exactly what I was hoping it would be. Never before seen behind the scenes footage of their most recent tour and albums combined with some great visuals and animations.
Is it going to blow you away or win major awards? Probably not. But in my opinion it achieved what it set out to do.
I liked the guerrilla (heh) style it was shot in, I liked watching the interactions between Damon and his band members and I loved the visuals that accompanied everything.
I'd recommend it to any Gorillaz fan.
