The Opposite of Irony

Is there a word for when something is expected to be ironic, but isn't?

Wikipedia has a thorough entry on irony, but shouldn't an encyclopedia entry regarding irony contain nothing about the subject? After all, that's what everyone's expecting. This is an instance when I would expect something to be ironic and it isn't. Then again, the outcome was the opposite of what I was expecting... the very definition of irony!

I guess the opposite of irony is more irony. That's honestly not how I thought I would end this post.
