I think it's ridiculous and narrow-minded (something you have accused me of being) to dismiss all EU reasons, as long as they are logical, reasonable, and don't make any far stretches where you have to do mental acrobatics (such as Padme making a Force connection with her daughter before dying shortly after, as I've already stated).
The EU is a broad category with too many sub-categories to count, not a single object (one book, one point, one author, one excuse/reason) that any reasonable person can simply write off as all bad. Say the first ice cream you ever tried was slug flavored, and then you dismiss ice cream altogether, saying you hate it. Well, slug flavored ice cream doesn't come close to defining ice cream as a broad category. So if you were savvy to there being dozens and dozens of more flavors out there, but refuse to consider any of them, that's what I would call narrow.
As you often do, you might come back with some point about how I need to accept that others have different views. Sure you have your views, but that shouldn't stop someone from pointing out how narrow those views are, especially since you're quick to accuse others of being narrow.
In Star Wars, there have been all sorts of reasons and excuses made up from the very beginning to explain things that weren't given much detail in the films. I agree that if a film gets too lazy (as the PT did in parts), then it shouldn't be excused. But those are only a part of the puzzle.
In this case, saying that Vader's seeming breathing inconsistencies are "a mess" is plain silly. What would you have wanted, Vaderisnothayden? Right after he was scorched by fire, have Palpatine immediately run up and put an oxygen mask over his face moments after? That opens up a whole can of other questions that would need explaining then. Would you have liked Palpatine, or some clone, or a droid, to stop and take up minutes of the film to explain what I did in my post above: "So, Lord Vader, my apprentice, I see that thus far you have been leeching from the dark side in order to keep yourself alive, and if your focus is broken for more than a few minutes, it will prove fatal. We've got to get you into a pressurized surgical chamber in order for you to survive your reconstruction... etc. etc. etc." Sounds like that would slow down the pace of the film substantially.
So tell me, Vaderisnothayden, in THIS CASE, how would you have supposedly handled it better than it was in the film?
If you cannot answer that question, and have no creative alternative of your own worked up, you're basically trying to use your opinion of "I don't like it" in a back-and-forth with nothing else to bring to the table.
