A very odd episode. The Picard plot is harmless fluff but full of holes. It should be far easier to have a strange behaving Captain relieved of duty than this. But then, by this point in the series everyone else in the crew is so used to having their every idea treated as moronic by the Captain they might be fully conditioned to behave that way no matter what.
The alien plot is utterly bonkers though. It ends with the Enterprise utterly failing in its mission and one of the delegates being eaten
. Which is played for laughs. It's hard to imagine any other episode ending with Picard being completely unbothered by a passenger on his ship being horribly murdered and cooked.
