Yeah my feelings are it isn’t so simple as one botched opportunity, more the dam busting after a series of unchecked cracks that started to add up over time. One of the bigger complaints about TROS is the breakneck pacing, but consider all the elements unresolved from the previous two IX now had to juggle or otherwise ignore like the Knights of Ren. All while trying to balance an appropriate ending to the trilogy, the saga, and being its own movie. So for me while it’s not blameless and I do think TROS took the lazy way out, it’s a tricky situation and some of it lands on time wasted not establishing more prior when there was time to spare. “We’ll figure it out later”, then all of the sudden we’re at the finale and later became too late.
