Due to how divisive Metroid: Other M was, nearly tearing the Metroid fanbase apart since it came out, Samus Returns appears to be this for Yoshio Sakamoto, who supposedly left the series. Judging by Samus' lack of dialogue and her characterization from Other M (very notably when she saw Ridley), it appears he took the fans' criticisms to heart.
Executive Veto: According to Sakamoto, MercurySteam originally wanted to remake a different Metroid game than Metroid II, but Nintendo persuaded them otherwise.
Thanks to the Metroid amiibo that released with this game, the Baby Metroid has forever become known as 'Squishy' for a majority of YouTube commenters.
