This Geordi episode is built around an interesting concept: virtual remote technology. It is a bit surprising that they didn't take the idea further, since even today our technology isn't far off from what we see here. (Perhaps they could have had Geordi interfacing with a five foot shuttle that could fly anywhere in and out of starships and covert into a humanoid-like robot; that would have opened up some interesting story possibilities!) Instead they attempt to make the episode more dramatic by making it more personal; we meet Geordi's parents. But all isn't as it seems... unless you've seen this show before, in which case you'll probably know where things are going and how they'll end about halfway through.
On the plus side, Marina Sirtis has a great scene, and Captain Picard gets to give a tongue lashing.
