I don't think its unfair to suggest an audience member can't ask the question. Of course they can. My perspective though is that its not the filmmaker's job to answer all questions that the audience might have. It is the filmmaker's job to answer all questions relevant to the story. And yeah, in the overarcing story, I think that the questions you suggest are important. BUT, when you're building a franchise film, one that honestly, we're following up on the previous one (ROTJ) from thirty years prior, fans are going to have a lot of questions. If you spend your entire movie answering questions, that might not be the most entertaining movie out there. TFA's job was to:
- Continue the Star Wars saga post Return of the Jedi
- Reignite the passion in old fans
- Bring new fans into the fold
- Tell an entertaining story
Of course, your mileage may vary on any of those. Is it perfect? Fuck no. But again, I think it did an admirable job.
Fans obviously want to know about Snoke, but as Rian Johnson suggested:
So questions such as who Snoke is, how did the saber get there, what's with the political dealings in the galaxy? I understand they're something that some fans want to but they're not
that important to the story at large.
