When Adam is hit by the police wagon on the cross street, a white car in the background moves backwards, indicating that the scene was shot with Adam standing up in front of the car so that it looks like he is falling when played backwards.
When Adam lifts the generator one-handed from Dr. Link, it bumps the back wall, revealing it as a flimsy stage wall. Then Adam shifts his one supporting hand to the edge of the shelf that holds up the generator. The generator swings from invisible wires holding it up.
Melody by a clarinet near the beginning twice makes the unfolding story seem comic, trivial and dismissive.
Accounts of the past given in court by Fred and Adam don't match up, creating a Roshomon situation of seeing through people's individual perspectives. Evie Cooper's is clearly inaccurate, as her testimony covers and conflicts with the opening scene of the episode. Mrs. McCrae's testimony, however, is an unknown. It appears accurate, but since Mrs. McCrae is a reactionary character, her testimony shouldn't necessarily be believed (and could have been exaggerated - yet doesn't seem to be).
The issue of Adam being a sentient being or a piece of property never comes up. Since one can't apply the term "murder" to a bit of machinery, it would presume that Adam is a being.
In lifting Evie out of the pond, Adam breaks her arm, yet she does not scream and shortly thereafter says "The tin man hurt me." For such a minimal, controlled reaction, she must have an unusually high tolerance to pain. It makes her courtroom reappearance in a cast seem contrived.
