- Critical Research Failure: The series is utterly riddled with them, pretty much relating to any culture outside of the United States.
- Hindus are depicted as revering the naga from the Source as gods, despite the naga in the Source having only vaguely superficial connections to classic Hindu deities. Even worse, the character who is bonded with a naga is mentioned to be a Sikh, who have a completely different religion from Hinduism and has nothing to do with snakes. This is akin to a Christian worshipping a pagan Norse god in terms of how inaccurate it is.
- Native Americans, particularly the Apache rebels, are depicted as revering the gahe shadow creatures as gods, which has utterly no basis in any actual Native American religions.
- Several combat scenes involve blatant tactical mistakes, such as goblin warriors threatening defended human positions with javelins, or any time a hostile flying creature gets in sight of a defended human position and isn't instantly shot down. At one point a Black Hawk helicopter is flying so low to the ground while shooting at invading goblins that an ogre can reach up and grab it by the landing gear.
- One bit of worldbuilding involves Fundamentalist Muslims functionally taking over Europe and forming a Caliphate there. This requires belief in historically empty threats of immigrants "outbreeding" natives that have been used for racist scaremongering throughout history.
- The Superhuman Registration Act has absolutely no basis or backing at all in the Constitution, especially as presented in the series, and is so severely unconstitutional that it would be thrown out almost instantly by any federal court, let alone survive for several years as it is shown in the books.
- The second book suggests for a time the US Coast Guard was floundering for a mission, between mages dispersing hurricanes and the legalization of marijuana. In actuality, disaster relief and drug enforcement are just two of the eleven missions of the Coast Guard and not even the largest commitment of money and man-hours. That and marijuana trade is one of the least profitable forms of the drug trade, with heroin and cocaine being the most commonly smuggled drugs via the ocean.
- Even Better Sequel / Surprisingly Improved Sequel: Fortress Frontier is generally viewed far more favorable than Control Point.
- Romantic Plot Tumor: Some of the readers feel that the relationship between Harlequin and Scylla that developed in Breach Point was at best a distraction and at worse entirely unnecessary and even forced on the story, since there were no hints of any previous connection on that level in earlier books, even when the two were present on the same military base.
- Unintentionally Unsympathetic: Some readers of Control Point disliked the protagonist for his Selfer apologism and the bad decisions he made in the novel.
YMMV / Shadow Ops
