So far, I've read:

The King plays are all part of a "War of the Roses" tetralogy, apparently. The first part started off great, reading like an action novel. After that, almost every single play in the tetralogy follows a pattern of being somewhat slow in the beginning, then building up to thrilling conclusion. King Richard III surprised me with its focus on an evil man's rise to power.

I found Comedy of Errors to be very funny. I was actually laughing while reading it. I figure Shakespeare is the one responsible for the simple Comedy premise genre, where the humor is derived from some rule or misunderstanding of some kind (character loses memory, character becomes a girl, character can't tell a lie, etc). It was very good throughout, but much like modern comedies, it suffers from the need to conclude the story in a way that feels more dramatic and formulaic than comedic.

The Two Gentlemen of Verona had one of my favorite characters so far: Crab the Dog. Lance's monologues regarding the troubles Crab caused him are hilarious. The climax of the play was also surprisingly dark, considering its lighter tones throughout. Between The Two Gentlemen of Verona and Love's Labor's Lost, I started to think that Shakespeare was the originator of the Chick Flick genre. Love's Labor's Lost actually reminded me of the plot for the movie 40 Days and 40 Nights, as well as How to Lose a Guy in 10 Days.

Finally, Romeo and Juliet makes a lot more sense to me now reading it in the context of Shakespeare's other plays. 

That's all.
