On the ONE HAND I understand they wanted to connect Discovery to TOS on a continuital level...on the OTHER hand-
-really?! We're just...REALLY supposed to believe that Spock not only had ONE sibling he magically never mentioned in Star Trek V with Sybok, but ALSO had an adoptive human sister in Michael who ALSO had a psychic brain link to their dad?! Like...WHAT?! GRANTED...YES Spock is a private person, and he canonically didn't talk that much about his personal life, but even so come OOOOOOOOOOOOOON.
UGH-I'm just so sick of the "Secret Relative" trope, its SO overused.
FOLLOW UP ON MICHAEL-how had Tilly never heard of a female Michael before? I've known at least 3, its not the most famously gender neutral name, but it is one. That one is more a minor nitpick admittedly.
AMAZINGLY-this doesn't stop me from liking the show, its fine, but UGH not needed.
