I generally like Sci Fi stories that have time and space themes. I have watched this episode several times. The first time I found it interesting for the theme and the story twists. As I watched it again and again I found so may inconsistencies that they started becoming more glaring: such as, Worf in the alternate realities share the same memory as the actual one but not the memory of each reality? What happens to the real Worf in each of the alternate realities? Deanna seems to say that he would miss the real Worf in one of the scenes, but is there not a Worf in that reality? When Worf finally takes the shuttle to close the anomaly where is the Worf in that reality? One would think that it would have been possible and not too difficult to plug these inconsistencies.
