A Star Trek work driven by a flag officer doing something stupid surely is unprecedented, yes.
At this level of magnitude, with such flimsy justification, yeah, it sure is... At least Admiral Dougherty had the demonstrable benefit to the entire Federation as his impetus for his part in the Ba'ku operation... Going after the Botany Bay to scare off the Big Bad Romulans from Teh Future is just weak from an in universe perspective, and sloppy writing from an RL perspective
If anyone has been following Peter Weller's career, you would realize that he has played a role as a "Star Trek" villain. During the series "Star Trek: Enterprise", Weller played the leader of a terrorist group.
Old, new...it's STO, they do what they want and bastardize whatever to get it. I like the Kumari...tough little PVE ship. But this is about the Vengeance...it looks hella ugly and it needs to be destroyed by a much weaker, superiorly crewed Enterprise. Oh crap, did I just ruin the plot??
