I have always considered the second season of Star Trek: The Next Generation to be my least favorite. The main reason being Diana Muldaur. She was a liability. I'm glad that she lasted only one season. Still, season two has some very good episodes. "Time Squared" is definitely one of them. I have seen it many times and each time I am very entertained seeing the story run its course. The climax of the story, where Picard confronts his future self, is very compelling. Patrick Stewart gives another one of his many excellent performances on Star Trek:The Next Generationin this episode.
