If you think the figurative death of a child and what that does to a couple is analogous (at least, from a drama standpoint) to what they had for breakfast, then yeah I can see why you wouldn’t like TFA.
I already explained that this subplot is not intrinsic to the rest of the movie. It is just melodrama thrown in to justify Han and Leia’s screen time for old-time’s sake.
If you want to make a film about 70 year old Han and 60 year old Leia and how they figuratively lost their son, then OK do that. But it would be a very different movie than TFA or any other Star Wars movie I have ever seen. Otherwise, they just needed to be kept in the background and played supporting roles that passed the story onto the next generation.
