That could be. I still have to read the last two. But for me (and I know I'm in a very small minority) nothing has matched The Gunslinger's brutality.
Avoid the revised edition. King added material tying it to the later volumes and attempts to retcon some inconsistencies, but actually introduces more inconsistencies. It sucks.
You know, when I read about that, I got SW special edition flashbacks, and was worried this might be similar. Thanks for the heads-up.
