I've gotten further into Wizard and Glass and just reached the section with Roland's flashback. So far so good. Haven't read through the Stand, but I loved the reference and am familiar with the story from snipets and the made for TV movie, which was good, but did cut out the ending with Flagg.
I have to say I don't mind the Tolkien references at all. King makes it very clear in the beginning that he was influenced by Tolkien in his being 19 intro, and that his goal was a Tolkienesque epic in the world of The Good, The Bad, and The Ugly. I see items like Blaine's riddles as simply as a matter of paying homage to the good old Oxford professor and the influence his work had, but I see also that King is unique enough to take the story and make it his own.
I think one thing that's interesting and probably will get more developed later on is the blending of technology and magic, something that helps combine the different elements together, from the western to the ruined future presented in Lud and even among Topeka in the wake of captain Trips, though lately the magic element has been sparse.
I for one cannot wait to finish Wizard and Glass (and now I can with a break in my finals) and still eagerly await my midnight showing of Return of the King at 12:01 AM on Dec. 17th. ^_^
