They call this a 'lesser work.'

How do you write a poem about a poem?

Why write poems at all
now that Fred Astaire has danced?

I'm in over my head
giddy dizzy diving downward.

Rhythm meter grace and beauty
Ginger Rita Cyd and Judy.

I really do think
that this might be
the prettiest thing
I've ever seen

which means

this can't be much of a poem.
