Maybe I'm in the minority, but I enjoyed this story to a point and even understood it.
The Irish Thing: At that time, that's how many people saw the Irish -- as an underclass. If the story is to be considered historically-understandable and somewhat accurate (see Steve's intro in EP145 for more on this), then the narrator's view of the Irish makes sense.
The Violence Thing: I was amused by the narrator's deadpan way he saw the violence he committed. It actually made him out to be a bit more sociopathic than some readers might have seen. He accepted violence -- shooting people nonfatally, beating Cathy, knocking out the guy the leprechaun was trying to menace to get away from the narrator -- in such a way that it was actually scary. In fact, it was played that he became MORE dispassionate when committing violence.
I accept that the story was seen as somewhat satirical by some, but I didn't really see it that way.
The constant interruptions from the White Street Society during the narration, I felt, took away from the story.
The names of the people in the society were hard for me to follow as well. And some of the imagery was pretty disgusting -- needlessly so. We didn't need the kids dipping their cups into the bucket or the excrement oozing up around the narrator's shoe. It was disgusting in there. We get it. Honestly.
I did like the way the story treated the leprechaun idea -- that they're not little cartoonish dudes who try to steal your cereal. Toward the end, I felt the influence of "American Gods" -- how the Irish brought the leprechauns to America with them.
Alasdair did an excellent job of doing the narration of the guy who went to Weeping House. I didn't care for the framing portions quite so much.
Overall, a pretty good PP.
