"31 is a Black Ops division."
Jeez, I really can't stand how the modern writers have made Section 31 an official arm of Starfleet. The entire point of the original idea was that it was a parasitic conspiracy hiding within the ranks, but not actually part of the ranks. Starfleet already has an intelligence agency for running covert operations, which is seemingly totally forgotten by modern writers.
The only time Section 31 has worked on screen after DS9 is when it appeared in Enterprise, because those writers understood how to handle an organization that existed as an under the table, in-the-know-only network.
Beyond that, I really, really, really can't stand how Section 31 looks like it is getting the glorifying treatment. It is not supposed to be a cool, awesome entity. Section 31 was a dark, broken, and ultimately misguided element. It was something to be overcome and dismantled, not celebrated.
Yeah Warhammer is pretty neat.
