Well, it worked. I heard (here) about the entire TNG crew coming back. I watched a YouTube video about it yesterday. The cynic in me says that Paramount saw the numbers for Picard dropping, so they made the announcement about the TNG crew now, so that people who've stopped watching or were on the fence would have a reason to maybe stick with it, out of love for the show and crew that brought Star Trek back from the abyss. It worked. I stopped watching two episodes ago (three now) but I watched Episode 4. It's still pretty silly. "New Guinan" is pretty bad. But there's less Q, which is good.
Fun fact: Episodes 3 and 4 were directed by Lea Thompson, probably best known as Lorraine McFly, Marty's mom. Going back in time, trying to right past wrongs, etc.
