Timeline wasn't his best. As Ant-Man and The Wasp lampoons in the subgenre, there is a habit of just throwing the word "quantum" on things instead of explaining them. Most of his other premises are much more grounded. Some are actually fiction and not science fiction. In general, he finds something technical and complex he enjoys and finds ways to explain them through a narrative, often with unintended consequences as a unifying theme.
