Answer:
John Milton was an English poet that was born in England in 1608 and died in 1674. He was best known for his epic <em>Paradise Lost</em>, and because of his strong belief in liberty and also in the right that people had to read and interpret the Bible by themselves.
The fact that Milton was born into a Protestant family, from the Church of England, was really important because first, it marked his belief in the individual reading and interpretation of the Bible, and second, because he almost became a priest himself. The second important thing about his family is that his father was an amateur composer, which marked and influenced Milton´s own passion for music and also the importance of it to his poetry later in life.
The answer is personal and spiritual exploration because romantic literature was meant to make the mind wander into romantic stories of love and romance where one found out more about themselves while falling in love. At least, that is my best guess since it's certainly not supposed to be rational and well reasoned ideas, it's not about religion, and I don't think it's supposed to empasise on society.
"Unsupported and exaggerated statements" would be something that best characterizes an unreliable narrator, but this is of course somewhat subjective.
I can just give you a suggestion of a story that I have watched. It's " How the Grinch stole the Christmas". The theme of the cartoon is that Christmas is not about presents. One evidence from the cartoon is that after Grinch stole all the presents from the people's houses, they were still happy and they were singing together by holding hands like the presents were nothing for them. At the end the Grinch realized his mistake and gave back all the staffs that he stole.
I hope it helps a little.
