I just read Gunslinger. Let me tell you. MEH. Pretty damn disappointed. My friend assures me that books 2, 3, etc., are much better. However, he also tells me that in order for them to make sense, I need to literally read every other Stephen King book. I have already read 11/22/63 and Under the Dome.
So - can someone kindly give me a primer here, which ones I should read? Where to start?
