i know there might be other love poems, but based on shakespear, what so great abou the poem sonnet 18?

Sonnet 18

Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer’s lease hath all too short a date:
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimm’d;
And every fair from fair sometime declines,
By chance or nature’s changing course untrimm’d;
But thy eternal summer shall not fade
Nor lose possession of that fair thou owest;
Nor shall Death brag thou wander’st in his shade,
When in eternal lines to time thou growest:
So long as men can breathe or eyes can see,
So long lives this and this gives life to thee.

Its eternal love for a withering beauty against all obstacles of Nature(e.g. Death, time etc.) since you believe that shs’s more beautiful than Nature(e.g. summer)
