You are absolutely right, but the problem isn't the lack of detail or nuance. the problem is making unnecessary changes that make believable characters unbelievable. for example: In this universe there are 3 VERY capable combat operators. and throughout the stories Ryan is the analytical planner. he figures out what is going on and sends in one of them, with a team of operators to solve the problem. Ryan is not someone good in combat, he is good with information not guns.
