Quoted from Roostking:
Will you at least admit it was a quick pivot!
Meh... I think Metallica showed them how big of a reaction and how well the market would respond. But it still took them 4 more years of uninspired stuff like GOT, Mustang, etc before they tried again with Yeti and Ghostbusters. I think Ghostbusters was the moment that while it was not the first, it was the moment around which people pivoted to embrace the art style as a lead feature again.
