Fair enough; I didn't have the same reaction, but I suppose that's just some form of values dissonance between us. The cloned mamluks from the prequels really rubbed me the wrong way, for example, but that didn't seem to be a common reaction.
Truth being told, it took me some time to figure out just why that scene felt so utterly wrong myself. When I first saw it, I knew something was off, but it took me a day or two to figure out the reason was that Poe had essentially violated a very basic concept of diplomacy.
The modern version of diplomatic immunity is commonly attributed to Genghis Khan, who responded to the murder of his ambassadors with the Mongols' signature "mountains of skulls" deal. You're right in that faking a diplomatic envoy is a dick move, but the Empire and Rebellion are already in a state of total war; it's only because these movies require their antagonists to be utterly exceptional that Hux doesn't just cut Poe off with a turbolaser salvo. Risking an enemy being galvanized to your total destruction isn't a big deal when that's what they're already in the process of trying.
That's certainly true, it really doesn't matter in the Resistance - FO conflict.
I'd just point out that the Resistance is only one of many players in this setting, the whole movie hinges on them hunkering down in some abondoned base and trying to phone some old friends and hoping they will come to their aide.
So, the whole galaxy isn't split into only 2 camps, there's several... but since neither Abrams nor Ruin felt a need to establish anything about this movie, we have no clue what is going on politically.
The OT didn't need to cover that aspect, but the ST should really address it one way or the other.
The Resistance will be forced to negotiate with someone who's not the FO sooner or later and they might even have an armed conflict or the threat of an armed conflict to deal with.
There's a traitor in the Resistance, which is how the tracker got there; Holdo couldn't be sure it wasn't Poe.
Since Poe is the guy who blew up the Megadeathstar, that's not an issue.
Or even if she was sure it was Poe, Poe has shown himself to be reckless and disregarding orders, he might unintentionally let knowledge of the plan slip.
Well, that last part makes a little more sense. Given Poe's actions in TLJ itself, just presenting him with any plan would have been sufficient and a somewhat decent one would not cause any issues whatsoever. He was reckless and disregarded orders, but that lead to a significant strategic victory.
As a counterpoint, I would present this idea:
How about Leia orders him to abondon the Dreadnaught, so they can get away quicker, Poe ignores that order, he destroys the Dreadnaught, but then the Supremacy with the tracker shows up and the fleet is fucked due to Poe's decision not to retreat. The point could be that causing casualties to the enemy was less important than to haul ass ASAP, this could highlight a difference in goals between Poe and Leia. Poe is focused on being a hero that fights the enemy, Leia's main priority is to keep her fleet safe.
Both want to win against the FO, but both have different priorities, based on their different positions. Poe has to order around a few squadrons, Leia has to take care of an entire fleet with some ships that aren't even armed.
That would set up a certain conflict for Poe and give him an organic direction to grow...
Oh god no, awesome effortpost and then this.
Vacuum doesn't shock-frost anything because there's no conduction or convection. It's not common-sense "cold", temperature as a physical property has an extremely complicated definition that kind of matches the common-sense concept in daily life (and even then, people say metal surfaces in winter are "colder" than wooden ones).
The only way things can cool off in vacuum is radiation, which is T quadrupled and laughably small on a mundane scale. A human in vacuum (with a breathing apparatus in a pressure suit) is going to die from heat stroke.
I am aware that vacuum has no temperature, however the atmosphere within the bomber would expand as it leaks out and thus cools down significantly. If I'm not mistaken, water on the skin also would freeze... I guess I was overdoing it by saying it would be "shock frosted", guess it would be more correct to refer to it as bloated, anyway.
