Beside critics, looking from the shoes of the one who is "supposed to be grateful", I can't see anything. There is occasional rhyme and tricky word combos that do call for some respect for the author but this is not art. Too much stress and accumulated hatred towards the "one who is supposed to be grateful" but isn't, grew to express itself in this form.

After all
Who plays the victim role
Wasn't the author the one who stole
Pointing his finger
When he was just supposed to answer a call
Is this poem ungrateful's one biggest fall
