This question is a matter of opinion. In light of this, let me give my thoughts. My three adjectives would be: slow-moving, blind, and tragic.
First, the town is, undoubtedly, slow-moving. Nothing much happens and more significantly, change is not something that is in the air. Tradition reigns for good or ill. Certainly when it comes to racism, this is a bad thing. Right from the beginning this note is struck.
There was no hurry, for there was nowhere to go, nothing to buy and no money to buy it with, nothing to see outside the boundaries of Maycomb County.
The town was also blind. Maycomb is not able to see that they have blindspots. The racism is pronounced, but they do not see it. An innocent man, like Tom Robinson, is made to be guilty and killed and very few people bat an eyelid. What makes it worse is that most of the people think they are good Christians. Mrs. Merriwether is a perfect example. She think she cares for blacks in Africa, but she does not care for Maycomb.
Mrs. Merriweather’s large brown eyes always filled with tears when she considered the oppressed. “Living in that jungle with nobody but J. Grimes Everett,” she said. “Not a white person’ll go near ‘em but that saintly J. Grimes Everett."
Now all of this is very tragic, because an innocent man, Tom Robinson and his family suffers. It is also tragic, because Bob Ewell almost killed two innocent children. What makes this most tragic is that at the end of the story, only a handful of people actually care.
