My favourite song from the movie as well.
I'm not ashamed to admit I haven't heard of the poet. But, poetry isn't my thing, hence the inability to be ashamed of not knowing it. I do listen to some K-Pop and I have a niece who watches the movie religiously.
Eh, who knows. Not everything's for everybody. Normally I'd agree with you, but I got really into this one.
Last year we took our 8-year-old niece to see the movie in theatres. It's the sing-along version, and we instructed her to stand on her seat and sing each song. We stood up and sang, too. It was fun. Might not ever do it again and that's fine.
