Absolutly love the Matallica performance in the concert portion of this movie. Although the side story is kind of confusing and doesn't really make sense, I think thats kinda the point. Its still very stunning visuals and an awesome soundtrack (of course). If someone say you shouldn't see this movie because it doesnt make sense then take my advise, see it. It's either you like this movie or you dont like it. Matallica is always a win in my books though.
