The ending is... interesting, if nothing else. That book was wicked sad. (Also -- I advise stopping after the "first" ending. You'll know which one it is 'cause it's followed, if I recall, by a big note from King telling you not to continue.)
I was really impressionable when I read the books, so they've all developed into people I admire. In a sense, I still want to be Roland. There are worse things, I guess.
