I also wish so much that modern Hollywood studio execs would see things this way, but unfortunately there’s really no reason for them to put in that extra effort anymore since they know moviegoers (at least for now) show up no matter what to a blockbuster tentpole. And the hundreds of millions of dollars will ALWAYS roll in.
The only “long run” studios plan for nowadays is how many more sequels they can squeeze out in the next ten years. Why should they take the risk of shaking things up a bit and finding a truly exceptional writer/director/cast, when it’s so much easier to pour everything into a giant marketing campaign? They just don’t have the patience anymore to actually make superior films. That era of Hollywood is dead unfortunately. (That’s why original content on streaming services like Prime and Netflix are really the only places to get the kind of movies people used to leave the house to go see.)
Movies that we pay good money for should always leave us saying “Wow!”
not “Meh.” 
Unfortunately, the majority of widely released movies these days elicit the latter emotion almost without fail. (Yes, I realize there are exceptions.)
Although I did enjoy the film overall, especially the Mark Hamill sections, the last scene of the kid looking up at the stars was easily the most memorable.)
Only really memorable moment in THAT trilogy was the last half hour with Smaug and Bilbo in part 2.)
