This is a concert film and the centrepiece therefore is the actual gig, the story feels a lot like an add on or break more than it does an essential or integral part but nonetheless is pretty enjoyable.
Seeing as the set is essentially a Metallica 'Greatest Hits' (although with quite a few obvious absenntees - 'Whiplash,' 'Fade To Black,' 'Welcome Home/Sanitarium,' 'Blackened,' 'Sad But True' in particiular) there is little room for a cohesive storyline which feeds off of the songs as Pink Floyd's 'The Wall' does, but it works quite well.
The sets are spectacular; 'Ride The Lightning's' Tesla Coils, '...And Justice's,' statue and the 'Master Of Puppets' sets are my favourites. Some are lot more stripped down e.g 'Creeping Death,' but the strength of the song and its performance makes it enjoyable nonetheless.
The extras, whilst plentiful are for the most part filler really. The Q and A session a the Orion Festival in particiular drags on and although I am a big fan of the band, found it very dull as it was only questions that had more or less been answered by either watching the film or the more enjoyable 'Making Of' segment. It could be interesting to some, but honestly, save yourself some time and buy the normal version without the dull extras.
