Star Wars: Rogue One - 10 Simple Blunders That Would Ruin It
6. Mass Survival
A rag-tag team on a suicidal heist: you can expect death as much as laser blasts in Rogue One. Well, hopefully - there is a risk that Edwards could baulk and a high proportion of the team will make it alive just because they're good guys. It seems pithy, but if everything goes super well then, in retrospect, the high stakes of this galaxy-defining story will be rather muted.
You see this a lot in modern televisions shows that claim to live by the "Anyone can die mantra"; The Walking Dead holds its original survivors dear, Game Of Thrones failed to definitively kill a major character last year and Lost even resurrected Locke so Terry O'Quinn could still get a paycheck. We've seen over and over in this Golden Age that showrunners get too attached to their heroes and actors too comfortable for death to be a threat.
With this film a standalone, there's no pesky multi-film contracts to deal with (presumably), but there is still a risk that Lucasfilm will want Jyn and co. to live through for further adventures in other media (that was, after all, one of the key reasons Han wasn't killed in Jedi - toys).
