Poetry is my favorite type of non-fiction literature -- I pretty much have no interest in novels or short stories, but read (and have memorized) a fair amount of poetry.
Poetry is abysmally taught at the school level, especially for aspie/analytical type people. Many people here might enjoy it more if they set aside the whole issue of "meaning" and "symbols" (which is all high school teachers seem to care about), and instead looked at structure and language. That's what's great about great poems: they are highly structured, patterned, and intricate.
Forget symbols, and look at iambs and trochees, trimeters and hexameters, masculine rhymes and feminine rhymes, sestinas and enjambment and terza rima, and all the good technical stuff. If it was taught that way, aspies might like poetry a lot more. (Maybe we should start a Poetry-for-Aspies class. 
BTW: "The Raven" is mostly trochaic octameter, a pretty rare meter -- did your teacher tell you that? (Better yet, ask the teacher what the meter is, and see if he/she can answer.)
