^ You don't have to watch it.
More and more I wonder why folks spend the time and energy writing negative-vibes posts on the subject. I am guardedly optimistic. In a bit over a month, I'll find out whether that optimism will be borne out or not. Until then, I'm not praising this as the Second Coming, nor am I decrying it as a waste of film stock.
I see lots of downer speculations based on pretty much nothing. Aftermath and Battlefront establish Jakku as its own planet, that is not Tatooine. Its significance is gradually coming out in the ancillary material, but I also expect a couple seconds of screen time explaining why the Empire and New Republic were fighting over it, so one doesn't have to read the books or play the games to know what's going on. I see not even the remotest hint that Luke has gone Dark Side. And we still don't know enough about Starkiller Base, who runs it, who's fighting over it, or how. We don't know if it gets destroyed, taken, or whether it remains for the entire trilogy -- but there's no "trench" in evidence on which for there to be a "run". A rift valley several orders of magnitude larger than Valles Marinaris on Mars doesn't count as a trench in my book.
