I get the impression that'sintentional in Leon's work in Home and Purlie Victorious. He wants people to experience a somewhat lost great work as it was originally experienced, as opposed to finding new things to say through the play.
Personally I've been finding the faithfulness a little boring, even while findings things I liked about both shows."
Well, if Leon is at his weakest directorially when trying to direct a show "as it was originally experienced", we probably shouldn't have to worry about that being an issue with Othello.
