It doesn't matter if you haven't read all of them, just pick your favorite out of the ones you have read.
Sadly I have only read Romeo and Juliet and Julius Caesar. Julius Caesar was kind of odd compared to the very well written (although annoying main characters) Romeo and Juliet.
Edit: Just read Macbeth for school, much better than Romeo and Juliet!

romeo and juliet my fav no doubt

Hamlet and Othello for the tragedies. Romeo and Juliet I just wanted to slap for their immaturity and lack of common sense. The only character I liked was Mercutio.

I've only read this and Romeo and Juliet...and I HATED Romeo and Juliet.

The characters annoy me sometime, but I like the narrative

It's the ultimate one for me.

So many good quotes, and SO romantic. I also love Hamlet.

I refuse to pick Romeo and Juliet which I loved but feel is overrated.

King Lear & MacBeth
