I believe most of the problem that people who dislike "Inner Light" find with it is this:
The story begins with a lone probe looking for one, single, individual to drill into their brain and make them live a fantasy life in their imaginations for half an hour and then gives them a nifty recorder for their troubles, when it's over. Yes, Picard's fantasy life as Kaman had a lot of Slice of Life moments that were very touching, like when he finally agreed to knock up his wife after five, desperately lonely years. Her reaction was cute and it does make me smile ... but there's just too much with this overrated episode to justify its overrated status in fan circles.
For me, personally, I can't single out any TNG episode as being so egregious that it's unwatchable, practically. But I'm not fond of any of the shows featuring Lwaxana Troi. They all tie for being super embarrassing to be made witness to. Put a white turtleneck on her, a black shirt and khaki pants and tone her personality down to dignified levels. That's how to approach a character of her supposed rank and "importance."
