"I'm not fond of rhymed poetry unless it's tremendously effective and suited to the content"
So then you will be satisfied with non-rhyming poetry that is not especially effective? Interesting. Discriminating and non-discriminating at the same time.
Har! A clever twisting of my words, but Lo I am not so easily pegged as that!
On the whole, I don't care for rhymed meter. It's an distraction from the start. When it's effectively suited to the content, or done exceedingly well, then it's an exception to my own rule.
Non-rhyming poetry that is well-metered is a personal preference. Of course if the poem itself is a simpering pile of doggerel, then that's another post entirely.
Quality precluding form, in every event.
