1. The Pym Particle (Ant-Man)
Ant-Man had to be the most fun Marvel movie to come out of Phase 2. Excitement levels were raised when Edgar Wright was announced as a writer/director and then dropped again when he left the project due to creative differences, but Peyton Reed stepped in to direct and did the project justice. When dealing with physics, however, it is always going to be hard to pull the wool over everyones eyes. Marvel's science-savvy fans have pointed out that the main idea behind the existence of Ant-Man is somewhat flawed. If the so-called Pym particle worked the way the film suggests it does by reducing the space between atoms in order to shrink an object, and increasing that space to enlarge it then the item in question would weigh the same no matter the size. This means that an average size fully grown man, or a man of any shape or size for that matter, simply could not ride an ant. Similarly, Darren Cross could not lift a sheep with just his thumb and forefinger, and Hank Pym would not be able to walk around with a 60 tonne tank in his pocket.
