The same titled book is on my wish and to buy list for many months now. So, when I saw that the movie is made, a documentary based on that book, it was time for me to see it pronto. Based on Harald Oimoen and Brian Lew’s book, this one offers nice insight into Bay Area thrash metal scene, probably the most famous thrash metal scene in the world, coming out of California. This movie is chronological, from end of seventies and all the characters being teenagers and starting their own bands with people like guys from Metallica, Exodus, Testament, Slayer, Dark Angel, Megadeth interviewed in the movie, nice tribute to fallen brother Cliff Burton and great live action footages, describing golden years of thrash metal through eyes of people who are still active in their respected bands and delivering killer albums. My personal opinion is, maybe the movie should have focus less on Metallica, more on other bands, and maybe more anecdotes less facts already known, that would make even better movie, although this one is good and fun to watch. I will get the book soon and see the difference between book and movie, I am certain that you can not put entire book into an hour and a half of movie.
