I noticed the same thing. We are at the end of Two towers and thanks to forcing those books onto my children (lets face it - they are quite slow and "boring" in comparison to normal children books) I have found new appreciation for stories contained in them.
But be advised that there are downsides to this - this time around I won't be able to stop myself from buying Frodos/Bilbos "Sting" when attending Fantasy Covent here in Warsaw (and its comming this weekend)
