I finally got a chance to see this movie. Jack Black is one of my favorite actor/musicians. Why? He's funny and talented! I guess I've been a fan since the Tenacious D HBO specials. I've been to a Tenacious D concert and I've bought Tenacious D stuff. So this review maybe biased. He was great in this movie. I thought this movie was very entertaining and the music was rock-a-licious!
