After going through all the Sonnets, I liked Sonnet 130 the most.
To be frank enough, I found Sonnet 130 a very odd loving poem. Rather than praising his lover, Shakespeare at first seems to be insulting her. According to him, her eyes do not sparkle like the sun, her skin is grayish-brown rather than white, her lips aren't very red, her cheeks don't have much color, her hair looks like wires, her breath doesn't smell very good and that the sound of her voice certainly isn't as nice to listen to as music. He also points out that she doesn't float like a goddess; rather she walks on the ground like everyone else but at the end, he tries to illustrate that his love for her remains undiminished.
