Stephen King is an asshole for what he did in the final Dark Tower.
King's reasoning: "Hm, let's take all these villains that took a span of twenty or more years to develop, all these villains who were meant to be unbelievably powerful, and let's just...I don't know, let's just be stupid and kill them off like cattle."
Reader: "Oh my God, this was horrible...well, at least the Dark Tower itself will be pretty awesome..."
*Right before ending of Dark Tower, Stephen King jumps in--literally--to talk to the reader.*
Steve: Yo
Reader:The hell? What are you doing here? Well, whtever. Sup, Steve.
Steve: Not much, Constant Reader. Do you want to get to the end of the Dark Tower (do you hear me sigh?)
Reader: Hell yeah, man! I mean, you've pretty much fucked everything else up in this volume, but you wouldn't make the awesome Dark Tower suck, too, would --
Steve: **** you.
Reader: Huh?
Steve: You heard me. **** you. It's not about the goal you pretentious bastard, it's about the journey. I don't write these things man, I see them.
Reader: ....What?
Steve: I'm trying to be clever in going about telling you that this is the shittiest book I've written to date. Oh, and don't write my hate mail, either. You know, I don't write, I see and record
Reader: ...What did you do?
Anyhow, yeah. I loved the Dark Tower, but the ending three volumes deserved so much better (though I did enjoy Song of Sussanah, don't get me wrong). And that preemptive strike against the readers just before the end to say that he knows he wrote crap and doesn't want to hear from us that he wrote crap? Yeah, no, but that's pretension on the highest level.
And now, looking back, I have to wonder why I went off on a rampage there. Either way, Blaze is a fun read, you'll enjoy it, but you won't remember it.
