Sadly, this episode doesn’t make nearly as much use of Frewer’s talents as it should. He’s not manic enough to be fun, not subtle enough to be convincing. Picard’s trust of him seems off somehow, like he’s going along with it because the script told him to, though at least Worf and Troi maintain their skepticism. It’s cute to see that few can resist asking him about the future, not even Data, and there are some other fun things, but ultimately the episode just feels meaningless.
Nowhere is that more apparent than in the very well-scripted scene in Picard’s ready room where Picard tries every rhetorical trick in the book to cajole assistance from Rasmussen. That’s a scene that doesn’t work after the first time you see it, because when you know that Rasmussen’s a con man, the scene utterly deflates, because there’s no moral dilemma for Rasmussen. What should be an interesting discussion about the philosophical and ethical implications of time travel instead becomes Picard wasting his time.
