This episode is, by far, one of the absolute best of the entire DS9 series. In my opinion, it is a "must see" for DS9 fans, and for Trek fans in general.In this episode, an accident on board the Defiant separates Captain Sisko from his young son Jake, and the balance of the episode tells the story of what Jake does with that separation over the course of his lifetime.In the timeline presented, Ben occasionally appears to Jake...but only for a few seconds before disappearing again. The brief, frantic, interchanges between this father and son over the course of many years is heartwrenching...and valuable lessons can be learned from them. Lessons about dealing with loss, regret, and the instinct to hang on to hope.Avery Brooks gives a stunning performance as Ben Sisko, and the actors that play Jake Sisko during various periods of his life do an excellent job as well. I give this episode 5 stars, but it really deserves more than that! A "must see".
