Just watched it and went back home in awe. It's not only because it was the most spectacular show i 've ever watched, nor because the back story freaked me out. It was because i realized that through the never i got a glimpse from future music entertainment.
Let me guarantee you some things about Through the never. -You WILL have a good time. -You will head bang. -You will grab the person next to you saying "this is surreal mate" -You will sing Metallica songs for the rest of the week. -You will start imagining other bands doing the same thing in the future.
But let me just say some cons -You will have a small headache, similar to the one after a loud concert -You won't see any plot -If you are not a Metallica fan or a metal fan in general you are in for a shock -If you are Mustaine, you will feel like crying again.
Seriously now, nobody should miss it especially in 3D. It is like a big concert video clip. It will change music live shows in the future. Metallica are still pioneers.
