Flint tends to be something of an idealist. The white hats are white has, and the black hats are black hats. If you see someone who is flawed with the good guys, he will either turn out to really have a heart of gold and simply have been mistaken and misunderstood. If you see someone who seems competent or honorable on the bad guys side, he will change sides (or remove ‘his’ group from the bad guys) in the next book.
If there’s a fight, knight vs peasant, bet on the peasant, or at least that the knight will be killed in the next few pages by a main character.
He’s also very groupist. If you have a person from group x, they will be honest, skilled, hard working…, at least by the end of the story.
But they are a fun read. They are also well researched and thought out (esp for mass market). It’s just that everything is through the lens of what the author want’s to true.
