How to evaluate Shakespeare's sonnets?

The university had the privilege of studying sonnets, and briefly talked about my personal views.

First of all, from the format of English poetry, there are concepts such as syllable, iambic, iambic and rhyme.

Shakespeare's poems are iambic pentameter, and light syllables and heavy syllables form a metrical step, just like China's metrical poems. Then there is rhyme. Shakespeare's rhyme is ababcdcdefefgg, which can be called "Shakespeare's poetic style", that is, the first sentence rhymes with the third sentence, the second rhymes with the fourth sentence, and the fifth sentence rhymes with the seventh sentence until the fourteenth line.

And what Shakespeare said in the whole sonnet set *** 154, I think it is Shakespeare's self-imagination. Shakespeare's sonnets are neither autobiographies nor descriptions of a character's life, so I don't agree that some people regard them as coherent autobiographies. These poems may not even be published voluntarily by Shakespeare, but collected by others without authorization and then published in a book, so we don't know why Shakespeare wrote these poems, who they were addressed to, and who they were compiled in strict chronological order.

Compared with his achievements in drama, his achievements in poetry are not so dazzling.
