Data's "mother", Geordi's mother and father, Beverly's grandmother, Jean Luc's "son", Worf's brother, and Deanna's sister. It doesn't sound like a long list, but it does skew season 7 towards that feeling of creative desperation.
That's not to say S7 sucked. It also had really great episodes. To varying levels, I really like Descent, Gambit, Attached, Parallels, The Pegasus, Lower Decks, Thine Own Self, Firstborn, Preemptive Strike,
and All Good Things.
