I was not thrilled by this episode--and this might be because I am a huge fan of Worf and so I tend to expect more from these shows. I almost always love episodes that focus on him (after all, what other member of the crew murdered someone in revenge and got away with it?!) but this one has a few problems--most likely the crazy twist at the end.
The show begins with Worf at wits end because Alexander is not a demented maniacal warrior like a good Klingon should be. When Picard hears about it, he recommends that Worf take his son to a nearby planet for a Klingon holiday celebration. Once there, Worf is nearly killed and he is saved by a family friend (sort of like Robert Duvall's relationship to the Corleone family). This guy sees Worf is upset about Alexander and tries to help the boy rise above common sense and cling to his berserker-like Klingon roots.
This isn't a bad episode...just the ending. See it...see what this dopey twist is and how quickly Worf just accepts this!
