Reading Shakespeare in high school put me off it for life. I had to look it up just now to check if he's "Elizabethan". I knew what most of the words meant, just not in that order. I couldn't make sense of what was happening in the plot, or even the smaller scale of individual lines. I never thought I was particularly bad (or good) at English, but all my classmates seemed to understand it. I just could not.
People rave about Shakespeare, so I'm sure there is something there. I wish I could have been able to get that.
