These replies helped me understand, and I appreciate it. One of the key reasons you guys object to the dialogue is because it's part of a larger failure to create a distinctly different era of SW like the PT had done. You're okay with everyone's dialogue being different within that context, whereas I object because I think some of those characters (mainly Anakin) should've sounded closer to their OT dialogue.
When the PT came out, I found the attempt to create a uniquely different era as being a leap in logic. To me, the 20 years between the end of the PT and start of the OT wouldn't amount to a completely different galactic aesthetic (and dialogue). It's hard for me to believe that an entire galaxy would have such a dramatic shift in that span of time. In many ways, the Empire would've carried over governance methods from the old galactic senate, so the change to imperialism wouldn't explain the total "cultural" and aesthetic shift.
Just one example: in the OT, you don't see a single ship with the sleek design of nearly all of the PT vessels. That's a little like saying that you wouldn't see any cars from the 60's on the streets in the 80's. You'd think some (even if just a few) of those Old Republic era ships would carry over. Instead, 20 years seem closer to 200 to me when I'm considering how thoroughly different *everything* is.
I'm fine with the ST carrying over the OT aesthetic because that makes more sense to me. A *lot* more, actually. I don't think it's lazy, I just see it as consistent with logical progression.
Like you guys, I'd prefer the humor not be modern and MCU-like. But it doesn't bother me as much because I expect each generation to have a slightly different voice. Like I said before, it would only truly piss me off if it was Han, Luke, and Leia doing that. But, Poe, Finn, and Rey? I can accept that their generation would sound that way, rather than saying things like "look sister, I ain't in this..." the way Han did in the OT.
Thank you both for clarifying.
I do actually understand your objections better now, even if we still see it differently.
An area of agreement!
Finally!
