Scholars conclude 'beyond doubt' that Shakespeare was main author of Edward III

I'm skeptical of stylometry. There just isn't enough data to make conclusive statements like this. Shakespeare wrote a lot of plays on similar subjects, and it's no surprise that a lot of words overlap.

That doesn't mean it's not interesting. I'm doing Richard II right now, which is unarguably Shakespeare, and Edward III an immediate prequel. It's too bad that more characters don't overlap. Edward and his son are dead, leaving Richard in charge, and the early death of his father (Edward's son) is an important factor in Richard's behavior (which leads to his downfall).

And sadly it's just not a very interesting play. I haven't read it closely, so perhaps there's merit there I'm not seeing, but I've seen it performed and it was just workmanlike. No great speeches, no memorable lines, no engaging characters.

Having an expert (this guy knows a lot more about Shakespeare than I do, and isn't just relying on statistics) endorse it as actual Shakespeare does make it more attractive to me, despite my doubts. Perhaps some day I'll direct it and find something really great there. I've had some great successes with rarely-performed Shakespeare plays. Opinions of his plays vary as tastes change: Coriolanus used to be one of his most popular, and now it's almost never done.
