Geordi emerges once again as the weakest character on the show. The writers just never gave LeVar Burton anything much decent to work with, and the result was almost always a contrived script that forced his character into behaving in inappropriate ways. This one with Geordi's mother could almost be the worst of the bunch ('Aquiel' wins that spot). It is great to see him without the VISOR, though.
Geordi comes up with a plausible theory about what may have happened to his mother, and for the first time ever - for no reason at all - none of his friends or colleagues are willing to believe him. It makes no sense. Really insane situations happen on board the Enterprise every week and LaForge is often instrumental in figuring out what's going on. I don't know if Burton picked up on what a weak script this was, because he doesn't seem to put much into his performance in this one. Similarly, the actress for his mother delivers something very cold and robotic - although that can be explained away by her being an alien. It still feels off.
Far better are the moments with the other characters. Riker's story about coming to terms with his own mother's death is touching, and Data choosing to help his friend is a powerful moment. Mostly, though, this is one to skip.
