i personally think that all poets are good within their respective natures though what some write may be cliched, or too general contain simple images, ect. though they might not capture a large audience...that certainly doesnt entail that their poetry is bad per se..., and keep in mind whom that person's audience is
...however i think the intent of the question is to ask, what makes a good poet, so much so that there is a general consensus that says...yes Edgar Allan POE is considered a good poet...with that in mind...then i would have to say that perhaps one has to realize what makes poetry work...u know fresh concepts...fresh imagery, and of course..practice i mean not all the poems by the greatest poets are at their pinnacle best (hope thats a word) ...some critics would say that they could have done it better...those are my thoughts anyway
"my love is my motivation
my love is my inspiration
perception of this poem
is your interpretation"
