This was a pretty good documentary. I did however watch it very soon on the back of watching the thrash metal episode of the 'Metal Evolution' series. Comparing the two of them, they both cover similar ground about the beginnings of Metallica and Bay Area thrash, and the rise of the "Big Four".
This documentary differed in that it showed commentary from other lesser-known bands like Overkill and Hirax, that it had some small coverage about the European scene, including interviews with Kreator and Sodom, and that it had some coverage of the "crossover" scene. This and the fact it had some interesting historical footage and photos would be the good points about this documentary.
The problem with this documentary was the preponderance of interviews with people from 90s metal bands like Slipknot, and various journalists and DJs who I would wager were still in kindergarten when thrash was happening. This seemed unnecessary. I did not care for these people's opinions.
