Lwaxana Troi visits Enterprise at the same time as a scientist from Kaelon II.
This is easily the best Lwaxana episode of TNG so far and is a pretty good commentary on the treatment of older members of society.
The plot is stronger and more serious than the previous Lwaxana episodes which are mostly comedy driven. There is a sci-fi mcguffin involved, but it is mainly focussed on the cultural practice of euthanising certain demographics of Kaelon citizens. In doing so it tackles an important and fascinating subject matter from a number of different perspectives.
Lwaxana's introduction is light hearted and humorous, but her character gets involved in a far more interesting situation than previous depictions. It is hard to take her seriously at times, but if you try to alter your normal expectation of light comedy it helps. Majel Barrett is excellent, playing her with more depth due to the subject matter. That being said, she most spends the episode whining about the situation, but it does end very memorably.
Timicin is a strong guest character who is not just a great foil for Lwaxana, but wonderfully portrays someone in a extremely difficult position. David Ogden Stiers gives a strong guest performance.
The final appearance of note comes from Michelle Forbes in a small role as Dara. In a short space of time she displays such a great presence and range that it no doubt convinced TNG producers she would make a perfect Ensign Ro.
All the cast regulars are solid, particularly Patrick Stewart and Marina Sirtis.
This is a 7.5/10 for me but I round upwards.
