Query: Wolves of the Calla is boring big-big

I've been a fan of the dark tower series since the early 90s, and I've liked them quite a bit. I cry ye pardon King, but Wolves of the Calla blew serious chunks. The beginning prologue is great (and has been available from Stephen King's website for over a year), and the ending is "interesting" (with interesting revelations made about the true nature of the "wolves") but the 600 pages in between are, simply put, really BORING!!! This is probably King's worst and most boring novel since the Regulators or the Dark Half. Unfortunately, in order to finish the series (with Song of Susannah and the Dark Tower, due in 2004), you must persevere and methodically blow through this most painful of DT volumes.
