I know that times have changed and I'm sensitive to the fact that, pretty much up until the Holocaust, anti-semitism was a fairly wide-spread prejudice and that Shakespeare (like Dickens) couldn't be blamed for contemporary societal perceptions. However, a modern reader may find this distasteful to the point of distraction, detracting from the overall quality of this work.
Is it a good play? Yes, it's technically quite good. But reader beware, the rampant anti-semitism may leave you angry and disgusted.
