LOTR vs Harry Potter

of course there are parallels, the Watcher of the water, and the giant squid, the dementors and the Nazgul, the Demetor's kiss, the balck brathow, but the plot, or setting is othing similar, so while there may be a few little things, she may not even have realized it! especially if she read them and really like them long ago, the picture would be in her mind for a new charcter or whatever. aslo, totally different, different class by far, comparing apples to oranges
