A slice of life with a shroud perhaps.
Is it dark? It's "dark" if a depressive life is dark, however, it is with a deft delivery and a keen sense of being that makes it good. Not excellent because it does take one above the norm. Yet, it speaks to the Heart and fibre of anyone who can feel its underlying throb, maybe that beat is a heart...this poem is real with Heart and well worth the reading!

Sorry, forgot to put "not" in the space shown below
"because it does __ not..." :)

I'm really messing up this comment and its correction, but I think you get the idea :)
