The Ro/Guinan scenes excel, regardless of age, but...
1) how easily the ship is taken over
2) In general, the story's structure is weak and overly contrived since this is only the Federation Flagship and all...
3) the big plot problem of Ferengi stranding only the adults to the surface? The 20th century was capable of doing better scripting than that! (A little added dialogue to add some tension and threat to justify this, since you know there's no way there would be incidental music to improve on the episode was going to be used, would have helped. You know, sell the little buggers off somewhere. The script has Ferengi stating they used a science team as slaves and stated the adults would be mining a lethal substance, which was middling at most, even more so because the little tykes can dig and kids love to dig (right?), but as the episode transpired the distinction of adult vs kid is only there to facilitate the solution of letting the kids save the day.)
are all pretty awful and even sub-part by season one's "finding ourself" standards.
That said, seeing the clothes being oversized for the newly-transported kids was a plus. The acting by the kids is certainly decent... and the Ro/Guinan stuff was inspired. I'm amazed Riker wasn't on Risa being duped by the latest toy walking to him slinkily as what had happened time and time before (well, once, but sex has been used by "the enemy" when it comes to espionage countless times. Risa should be off limits rather than a frequent flyer club!)
Plus, why not, I chucked out of "You're my number one Dad!" Picard thinking on his feet.
There are readily worse stories, but most of those times they're not contriving situations so badly.
