Personally, I am against the making of COH movie. It is quite different than LOTR, and addresses much more powerful themes. I consider the LOTR movie a disaster - and I'm afraid to think what COH could turn into

.
I don't think that COH contradicts with LOTR. It is my belief that Tolkien (unintentionally, perhaps) summarised our world in his books. Although LOTR is not exactly a "hobbit walking-party", jokes are added in good measure, and lighten the atmosphere (as a whole) significantly. COH is totally different: although there is less description, it goes deeper. To say that - I'm not saying that LOTR isn't deep, - even the hobbit-jests are deep in a way - but it's in a different way than COH. I don't see how adding a different theme to his creation would make a dent in Tolkien's works, especially if you see the as I do.
