With all understanding, this is a bizarre comment.
Why someone here wants to read that novel - because that novel is cool. You just have to read it in the language of original. There is way more life in it than in Childe Harold IMO. Closer to Schiller, I'd say. Lots of subtle sense of humour, multi-dimentional, very sharp. Classical, not romantic. In fact Pushkin compares Onegin with a bit of humour to Childe and calls romanticism "dark and sluggish" when he writes about the Lensky's last letter. The real heroine is actually Tatiana, the novel follows her path and ends with her keeping her purity in accordance to her self-ID while being completely honest about her feelings to Evgeny and mournful for lost happiness. Kinda like The Maid of Orleans follows Johanna's path and ends with her staying true to herself as a woman of her belief about her destiny and a person of her nation despite her romantic love for an enemy. But it's because Onegin happened to meet her, Pushkin "gets a chance" to write about her and we get a glimpse of her life and person, that's how it's realized. There is a lot about country life, its simple delights, which were also Pushkin's and Tatiana's delights, and about circular life of high society and its emptiness, but through the feelings and perception of an individual. Which brings us to the next point: he was the first to stop writing odes and start writing about normal people with normal feelings in normal language - about as much as Dante did if not more. That's why they read it. You probably read the plot of it on wiki, that's why you are wondering. I also understand the hard feelings.
Why western people cling so much to that "culture" - it's not "culture", it's culture. Western people don't. My experience most westerners only know works of Solzhenitsyn and Nabokov, but it's actually American culture. So they stick to their own culture.
