First, I don't think highly of the original story, and I imagine this predisposed me to not liking fanfiction based on it.
While I enjoy EY's other fiction -- in particular, Three Worlds Collide, and the short beisutsukai stuff -- HPMoR doesn't have the same punch. It's a bit like Atlas Shrugged in that he tries to sum up the entirety of LW philosophy in fictional form, and the result is a text that drags on and on with little thematic unity. I enjoyed parts of the Ender's Game chapters, for instance, because they were more or less on topic the whole time.
All in all, I would rather reread "Shinji and Warhammer 40k", "To the Stars", or other really good fanfiction than bother rereading HPMoR.
This is the monthly thread for posting media of various types that you've found that you enjoy. I find that exposure to LW ideas makes me less likely to enjoy some entertainment media that is otherwise quite popular, and finding media recommended by LWers is a good way to mitigate this. Post what you're reading, listening to, watching, and your opinion of it. Post recommendations to blogs. Post whatever media you feel like discussing! To see previous recommendations, check out the older threads.
