So did I! Thanks for the company.
From the moment, Gollum appeared in The Hobbit, and especially his romp through The Two Towers, I thought he was the best written, most fascinating character in literature (with the exception of Sydney Carton from A Tale of Two Cities).
If you want to know if Dickens is a genius... look at Carton. If you want to know if Tolkien was a genius... then look at Smeagol. Truly, great writing.
