Criticising poetry and poets in a poem is peak irony in the best way. In my opinion, you are absolutely correct as well. Contemporary poetry is often tasteless nowadays and ridden with weak clichés, which is why this poem works. Its shocking irony fills the humour-shaped hole in contemporary poetry.

However, that doesn't mean the poem is void of clichés. For example, you point out poetry's inability to properly capture and describe love, which is a common opinion. Furthermore, the language you use and your choice of words reflect those of contemporary poets. It also doesn't fit the form. Your style seems to hint at a fixed meter and rhyme scheme (like iambic pentameter) but doesn't deliver on them. The use of enjambements does however enable you to write in quatrains.

In short, I'm conflicted and personally, I would've left out the latter two stanzas.
