That’s just, from my point of view, Rian Johnson doing whatever he can to destroy everything that’s within his reach simply because he can, to prove some sort of point to someone.
Seriously?
That’s going a bit far.
It didn’t seem like he was destroying things just because he could (to me, at least). It did seem like he was continuing or building importance of things only to make them unimportant for some shock value. It would be the equivalent of the big “twists” of ESB (Vader=father/another hope) only coming after intentional misdirection. Like if Luke had been killed immediately into his battle with Vader, only to have Obi Wan reveal that there is another Skywalker. You are shocked by Luke’s death and then confused by this revelation and left wondering “what was the point of the last film and a half?!?”.
It isn’t “bad”, I just don’t think it holds up over time and you risk losing the viewer because they stop being invested when “nothing matters”.
