The more complexity you introduce to a plot device the more sense it has to make to be satisfying. Nothing in the OT has the level of complexity of Starkiller Base or how it operates. The Death Star is just a big "turbolaser" which is just a big "blaster." The details are never explained because they aren't important. Starkiller however is explained just enough to make the audience aware of how little that explanation makes sense.
Yeah, there was no need to over-complicate the big gun. It came across as JJ trying to pretend that the SKB was different from the death stars, which it wasn't at all. It was the exact damn same, just with JJ's bigger = more drama nonsense tacked on to it. I swear JJ has the worst case of short man syndrome I've ever seen.
My real problem with it wasn't how it worked, that's ultimately irrelevant. It's why does the Empire or it's offshoots keep killing off tens of thousands/millions of it's personnel by making these things so easy to destroy?
Ok, the first Death Star is a design oversight. The second one wasn't actually finished. Fine. What's the excuse here? A critical component can be accessed from the surface by both personnel and starfighters, and the failure of that ONE component destroys the entire planet. The Imperial Corp of Engineers is terrible at it's job. Terrible.
There are apparently no backup systems either. What if that regulator thing just malfunctioned? One component craps out and the whole thing implodes.
Oh man It's Delta Vega all over again.Seeing Vulcan implode from the surface. That's some good times right there.
I'm wondering why Abrams keeps doing this. It's such a basic thing to get wrong. Everyone knows you can't see other planets as giant orbs in the sky because - well - we can't see them in real life. He easily could've had Spock feel the destruction of Vulcan - sort of like how he felt V'Ger. He could've easily had Leia feel the destruction of those planets with the force & it would've been arguably a more emotionally powerful scene and a call back all at once. Luke & Obi don't see Alderan destroyed in the sky of Tatooine. So is JJ just unable to communicate a scene that way, or is he actually a dumbass?
