I'll add another +1 to the list of people assessing The Stand as Stephen King's best work. If I had to develop a top five list of his novels, I would say:
1. The Stand (What more needs to be said?)
2. Bag of Bones (A ghost story, but not strictly a horror novel. Includes one of the most affecting character deaths in any of his novels)
3. Wizard and Glass (The Dark Tower series peaked at this point and, unfortunately, took a rapid dive in the following book)
4. The Long Walk (as Richard Bachman. One of his view novels I've finished in one sitting)
5. Dreamcatcher (The friendship between Jonesy, Beaver, Pete, and Henry is well-realized, and the scenes with Mr. Grey in Jonesy's head especially stand out. Also, shit weasels)
