I think the catalog is razor thin. It's the debut....and not much else. Though a single album discography hasn't been a disqualifier in the past.
Legacy? Maybe. I think the Dolls, like the Melvins (an unfair comparison, but bear with me), may have paved the way for others who got way more time in the spotlight. Perhaps, in the Dolls' case, the acts that followed were actually better.
Me, I'd rather listen to LAMF than the Dolls' debut.
