I went through a big Shakespeare phase- by big, I mean that I read four plays of his: Julius Caesar, Hamlet, Othello and 12th Night.
Each of these (especially the first three) was a major undertaking and I quickly began to prefer editions with many liner notes so that I could understand more of the connotations of Shakespeare's expressions. I loved his language, much more than the English we speak these days. And while it is true that the plots are often simple or trite when summarized, they provide the context for powerful characterization- I do not see the point in a plot if the script does not bring it and its characters to life. Yes, it is true that Iago's motivations are unclear and seem more like a plot device than anything else. Nonetheless, I suffered for Othello and Desdemona as I saw the former be betrayed in that his heart was poisoned more and more by a trusted compagnon. I suffered myself, really, as I felt helpless to prevent the inevitable tragedy- I suffered, while reading a play in book format- with no background music or images before me. That is powerful characterization.
I love the Chrono series. Cross in particular has a very unique and beautiful atmosphere through the images, music and spontaneity and individuality of the plot and characters. But as much as I am fond of all of that, or of the character of Kid or Glenn or Nikki or Fargo... not one of them is presented as powerfully or as thought-provokingly as Othello or Hamlet. Not one of them makes a speech as ravishing as that of Marc Antony denouncing Brutus and his followers. Not one of their tragedies cuts so deep and as the death of Desdemona or leaves one with such a sense of futility as that of Hamlet.
However, I would also like to take this opportunity to mention that people who are able to appreciate the plot of the Chrono series have a somewhat rare openness about them. In Shakespeare's time, most if not everyone would have held such a plot for nonsense- and most people today are the same. What, magical kingdoms on floating islands in the dark ages? dimension splits and doppelgängers? It's easy for them to dismiss these things as gimmicky fluff- however, the fans themselves appreciate this inventiveness and the heart behind it.
