These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Angst? What Angst?: Both Sinbad and Nala lose family members they were close to but seem to get over it in a short amount of time. Might be somewhat justified in the case of the former since they’re comforted by their brother’s ghost.
