I think the film was a lot like Season 1 of the show, focusing on the war side and there's even some similar themes (the writer Allan Heinberg is a fan and when he wrote the Wonder Woman comics he adapted a lot of stuff from the show).
And I think the second film will also be similar to the 2nd/3rd seasons of the show in relation to the Cold War/Spy stuff setting (which was also similar to the comics in the late 70s/early 80s). This was what Heinberg mostly incorporated in his run on the Wonder Woman book, with the DMA, while also referencing the 60s spy Wonder Woman.
I hope there's at least a nod to the IADC and/or the IRAC computer, which would be appropriate for the setting.
