MoR can be construed as parody of Harry Potter - in fact, a lot of reviewers point specifically to where it pokes fun of holes in Rowling's worldbuilding, and (as noted elsewhere hereabouts) a major theme is the reversal of Rowling's stance on death.

Actually, I will say that I thought of it as a parody myself at first, and even described it to other people as a "spoof". However, I feel that it has grown into more than that over time, as the story has developed. At this point, the original seems almost irrelevant. (My personal familiarity with the canon is limited, but people have told me that it pales in comparison.)

(Understand that I find it utterly perverse that what ought to be a profound compliment amounts in this peculiar context to an argument "against" the story.)
