Yes, we are. If you think Metallica peaked in 1988, well, ok. But even if they did, even post-alleged 1988 peak (self-titled 1991 album may have something to say about it), any Metallica album has sold more copies than all of the albums by Cojira combined. Metallica has sold more albums than Cojira in France.
I take it you liked the opening. I didn't. Hot mess. Personally, after watching the Beijing opening ceremony, or even the London ceremony, I can't see how anyone could not think the Paris opening was a hot mess. But yeah, to each his own.
