I'm a music freak - I luv music. So most music related movies intrest me. School of Rock was somewhat childish but great nonetheless. And then comes Tenacious D and puts the Pick of Destiny in view of the world to see its awesomeness. The playing in this movis is really good and well, funny. The opening song is hilarious and the little JB living in "Kickapoo" is the living imatation of a young Jack Black.
Even though the story tends to get a bit weak in the middle of the movie, it picks itself with a Satanic Rock War and funny "devilish" scenes. Alltogether very creative and extremley hilarious!
