Well, sorry l can not read all the post but l would like to give my opinion too, as l did before the first thing is apologize my english level... lm a selflearning one.
I didn't like it either, l hate it too... why?
A lot of reasons.
First l must say how bad I feel about his hit accident when it happened, but, l am the only one that think SK is writting different since then?
I love the Dark Tower series but l prefer the pre-accident ones.
But the last one...
Why SK himself does appear in the book? why is he talking about his accident again? why did l feel like all magic dissapear when Roland speak with Stephen King?
Why the bad guy is out with that weak end, after chasing him during all SK novels?
Why kill the guys, and recover them, and kill them again, to show them alive again in last pages?[spoiler]
I would prefer a no end, not a forced one.
I would love express myself better, is dificult for me in english, but l think you are going to get the meaning.
Anyway, l still love all stephen king's works, l adore the comics of DT, but... this seventh book will be always a knife in my heart.
