Part of what makes Anno and Higuchi’s Shin Godzilla 5th form so scary is Godzilla’s ability to rapidly evolve. Released in 2016, Shin Godzilla is the 29th installment in Toho’s Godzilla franchise and the 31st Godzilla film overall, counting the American movie released in 1998 and the MonsterVerse version released in 2014. Co-directed by Hideaki Anno and Shinji Higuchi, Shin Godzilla serves as the third reboot of Toho’s franchise and features what some fans and critics have hailed as the most terrifying version of Godzilla yet.
