How does Metallica Suck?

They don't. People just get jealous of their talent. That's why Metallica's albums sell so good, because they're musically better then underground bands. People say that St Anger, ReLoad, Death Magnetic, and every album after the Black Album sucked, but the only way they might suck is in comparison to Metallica's best songs. Fuel is still gonna be better than anything these haters could ever hope to compose. The Day That Never Comes is always going to be more popular than the unknown metal bands songs, etc.
