I’m not sure SW is trying to be anything except long lasting and successful?
It does but what’s required to do that long-term? What has enabled superheroes, Trek and Bond to keep going over an extended period of time? I think the answer in part is a certain flexibility where continuity is concerned. In contrast, Wars tends to try to resist engaging in that flexibility, which is a double-edge.
Positively, it sets Wars apart from its competitors; negatively, over time it can become more and more difficult to manage. Eventually, it took just over 20 years, Legends did run itself into the ground. In contrast, superheroes regularly reboot, either overt or covertly.
Disney’s strategy thus far appears to be limiting the stories for any one era and organising it by era blocks – it’s not a bad strategy, might work for a time – if all Disney wants from SW is money at an achievable level, it might suffice. If they want far more profit out of it, that might become more difficult. The big challenge isn’t making money out of the ST, that’s done – it’s the post-Skywalker material that is more of a wildcard. It’ll still make money, that’s guaranteed but what’s less clear is those corporate expectations.
