Overrated? Absolutely not, listen to their first seven albums plus some gems post '88 and then let's talk again. A career built on the same power chords? You're confusing them with the Ramones.

They've had their dark moments (Virtual XI above all), but if they’re not one of the best metal bands out there, then we’re in trouble.
