Happy Endings

From Playwriting Seminars 2.0:

There's nothing wrong – and in fact everything good – about a happy ending if that's the logical outcome. The problem with happy endings is that more often than not, they defy the logic of the story.

I just want to note that the same ending can be tragic or happy, depending upon who the protagonist is.

I have to say
that if only the play
was mostly about MacDuff...

the death
of MacBeth
would be happy enough.
