Hmm, I quite like Harry Potter, but of course she copied Tolkien, he is the master... he was the one who made the genre hugely popular, before LOTR fantasy as a genre was nothing, without him HP probably wouldn't even exist.
Anyway, LOTR book and movie are a million miles better than HP... or any other book or film, IMO.
Oh yes and isn't LOTR more popular now, I bloody well hope so, second highest box office ever, second movie in cinema history to break a billion, 11 oscars.
As for the books, in fifty years if HP is still read by millions (doubtful, to say the least) I might be impressed.
