10 Movies That Struggled To Define Their Own Rules
1. The Science Of Shrinking - Ant-Man
Much like the wavering strength of Captain America's shield, trying to make sense of Ant-Man's (Paul Rudd) shrinking and embiggening is a thankless task.
The first movie explains that the Pym particle shrinks a person down while still retaining their mass and strength, as supported by numerous sequences in the film where Ant-Man's mass is very clearly that of a full-sized person, namely his ability to still punch humans with considerable force while tiny.
Yet there are also numerous sequences where Ant-Man is traversing surfaces which could not support the weight of a man, not to mention riding on the back of an ant which should surely be immediately crushed under his mass.
That's not to ignore the smaller objects which are enlarged throughout the film: if the Thomas the Tank Engine toy retains its diminutive mass when enlarged, it shouldn't be possible for it to smash through the side of a house and crush a police car.
Though it doesn't sink the entertainment value of the Ant-Man movies much at all, the lack of consistency is a bit annoying, if perhaps somewhat necessary for the filmmakers to make the most of their wacky central gimmick.
