By very strange coincidence I received two independent requests for review recently for almost the exact same thing - interactive Shakespeare for my iPad. Here's the thing, though - one is an interactive book, and one is an app. Other than this technicality they are nearly identical both in function as well as what they hope to accomplish. As such I cannot help but review them against each other. Here we look at the app.
Read the plays or see them performed?
It's a question we've beaten into the ground over the years and my position has always been that it's the "or" that causes trouble. You absolutely positively without doubt should do one and the other. The constraints of daily life are what decide which you have the better opportunity to accomplish.
Presumably Gregory sees Tybalt approaches, which is confusing as it is Benvolio who arrives first. This could mean that Tybalt is seen by Samson and Gregory, but is positioned so as to surprise Benvolio.
