This week, Matt and returning guest host Laurie navigate through the minefield of “Project Daedalus.” There were lots of good character moments, and we loved finally learning about Airiam, but we weren’t so happy that this all just happened for the first time now. In a TV show that is supposed to be serialized, we’d have liked to have seen Airiam’s character growth sprinkled in all season long. Michael and Spock’s continued icy estranged sibling relationship was another highlight of the episode; Ethan Peck and Sonequa Martin-Green nailed it. There were also a few scenes that didn’t quite feel right, as if the script needed another pass or two to polish it up, but they were carried through by the consistently excellent performances of the cast.
