I personally won’t see TROS in the theater. I didn’t go to TLJ either.
No doubt there are what could be called hardcore fans who have no interest in the St altogether. But here’s my question, for someone like you, would watching and enjoying the Mandalorian make you more likely to see TROS in theaters?
For me, skipping TRoS is an easy choice because I didn’t like TFA all that much and I liked TLJ even less; any movie by J.J. that has to clean up after Rian is unlikely to interest me either.
To your point, Mandalorian is its own thing and enjoying it wouldn’t affect my decision to stay home for TRoS (just like my dislike for TFA/TLJ won’t stop me from checking out Mandalorian). I’m sure there’s a small minority of fans who are just done with all Star Wars at this point and will skip all Disney SW, but…
I’ve been reading and listening to hardcore SW fans for 40 years. I know that most that talk about not seeing a SW movie or TV, book series are blowing smoke. When the product is released, they get it, watch it.
