I have read and seen Much Ado About Nothing. Its theme is more complex than love, lies, and denial. Any ideas?

I saw the play tonight ( tomorrow at two p.m. is the final performance), at CSUEastBay in Hayward and it was so real. I have read the play previous to this in a Shakespeare cl so I know the storyline and characters well. What I need help with is the theme not the story. What is it really about? It is more than denial andfinding true love. It is more than plotting against purity, isn't it? What do you think that the underlying theme is of this play? I read a comment which was posted monthes ago that mentioned the idea of nothingness, hence the title. What do you think? Thanks for considering this and responding.
