Answer
Pinkerton, Weezer's sophomore album, was initially a commercial disappointment due to its darker and more experimental sound, which deviated from the band's debut album's pop-punk style. Critics and fans alike were initially polarized by its raw emotions and unconventional approach, leading to lower sales compared to its predecessor. However, over time, Pinkerton gained critical acclaim and a cult following, becoming one of Weezer's most celebrated albums.
