I hear the band was a little pissy about being asked questions about their music instead of their IMAX film. A film revolving around their music. Never mind that the band really isn't relevant in terms of Comic Con, but ya know...love the guys, but shut up and have fun.

I won't comment on how I feel about there being a plot in this movie. I just won't. You know what they always say about saying nice things..
STILL, Metallica also played a "secret" show while in San Diego and it included this performance!
