This isn't actually the same book that I have, the but the title is the closest that Goodreads has, so I'm hesitant to really review it. However, I imagine other collections of his work are somewhat similar.
Short version: some of the stories felt compelling and tense and interesting. This only made the others seem even more dreadful by comparison. "House of Usher" itself was pretty hard to get through the first time, although on second read it improved.
My version of this book ends with the "Narrative of A. Gordon Pym," a novella that takes up almost half the book. It began very interesting and reasonably paced, without all the drudgery and portentousness of some of the other stories, and got quite tense and exciting. Then it suddenly morphed into a mind-boggling boring travelogue (complete with details about the cut of the sails and the longitude and latitude that day) for a really long time before once again shifting into action and adventure, and then ending weirdly, with no real conclusion. At points I thought perhaps Poe was just messing with me, daring me to keep reading no matter how bad it got (ha ha, you stupid girl, you're totally falling for it). Maybe he was, and all the supposed faults of this difficult book were a ruse to trick me into writing a bad review of a classic and beloved author, who everyone knows was brilliant. Well, he got me.
