I think part of it is just that a stormtrooper is saying the line, and not one of our heroes. The original Star Wars had humor, but usually through the heroes, droids, or aliens, and not too much at the expense of the Imperials. The Prequels started a trend of Star Wars villains and henchmen being comic relief (obviously the Trade Federation droids and leaders, but even Palpatine’s final battle against Yoda is just plain comedic), and I think carrying that into the Sequel trilogy where we’re back to stormtroopers and Imperial aesthetic has put some people off.

Since Hal removed most of the villain comedy from his Prequel edits, as well as some of the gags in TLJ, I’m just wondering if this line is tonally appropriate for what he’s going for here. Like axlanian said, it almost feels like something out of Red vs Blue.
