The other day I posed the "Which play would you skip" question, and said I would not bother reading/recommending King John. Several people jumped to the defense of the play. So I was particularly interested in the above blog, who also asks "Why read this play?" After, I'll add, saying "It doesn't take a rocket scientist to see why this is not one of Shakespeare's more popular plays."
No mention of The Bastard, by the way.
