Both I studied in school, which obviously really helped my understanding of and thus appreciation of those particular plays. I think Hamlet is a really interesting character, the ambiguities of his sanity and motivations in particular. I mean, the whole play is basically his thought process with some extra stuff (i.e. murders) thrown in there.

With Othello, I thought the role of Iago as the "secret villain" was really interesting, and also the whole thing of who's the blame for what happened, Iago or Othello? Desdemona is kind of irritating, but for me the mind games between Othello and Iago make up for it. It's just a really interesting story.

Romeo and Juliet is just really boring to me, I'm not a fan of the whole star-crossed lovers thing.

King Lear I read on my own last summer, and I thought it was interesting - particularly in the different presentations of women - but I didn't read it as carefully as I could have, so I don't have much else to say.
