I think they should've approached the opening part on Saddam differently. They basically made it out that he was a good guy, which he wasn't. Our reason was for going in there was 1, intel gained by torture, and 2, faulty intel that said Saddam had WMDs. Anyone who watches that with background knowledge on Saddam will be immediately skeptical about the rest of the video that followed.
A short read on the subject to show more complexity:

Basically I don't think 12 minutes is enough time to cover ISIS's rise in any sort of detail that would actually explain the rise of ISIS.
