Um, this thread has kinda been done hundreds of times before, but I'll post anyway.
Harry potter is extremely similar to LotR, but SO WHAT? Its clearly almost definitely NOT a coincidence, but I must say I loved the harry potter books. If JKR did in fact copy soe things, then she has done a good job of transforming them. I mean the whole overall plot of most stories is the same: GOOD

vs EVIL

good. If it was completely unimaginative, THEN I'd let off steam!
