Does it actually say that about the reactor in RO (genuine question, I’ve only seen the film once)?
Aren’t volatile reactors all the rage throughout the saga? Anakin blows up a Trade Federation ship by accidentally hitting the reactor with big torpedoes. Death Star II is all about hitting the reactor. The Super-Star Destroyer cops it in the ol’ reactor too!
Look, I get it. Many fans didn’t think the initial Death Star takedown was plausible, and RO supposedly answers that age-old question. But I never had a problem with the exhaust port. It was an audacious plan on behalf of the rebels that actually turned out to be a failure (see Red Leader, his targeting computer, and a conga-line of dead guys that didn’t even make it that far). Luke Skywalker was a complete and utter wild card. It makes infinitely less sense to me that a saboteur planted a weakness that required extremely creative analysis (assuming all the construction crews and technicians and overseers never noticed the flaw), was more or less impossible to exploit, and ultimately relied on the Force re-emerging as an option.
