I like the guy but like a lot of you he lets me down with his endings. He starts off strong and has some very good ideas but it seems that he just fizzles out and wants to hurry up and finish the book.
I've read a lot of his work but I also still have a lot to read. The Mailman, The Ignored, The Store, Dominion, The Summoning, and The Association are sitting on my shelf waiting to be read. The Walking I liked, ending not so much, but thought it was almost as good as The Revelation. I haven't bought any of his newer books since he has let me down.
With me he is one of those authors that you buy the books and they sit around for awhile and then you get the inkling to read him and go through two or three books at once and then you find yourself not wanting to read him for awhile. Ann Rice is another one of those authors for me as well as Keith Ablow and John Saul.
But you know Koontz has done this sucky ending with a few of his books as well. The Taking was a good book but by the time the ending came I was like "You got to be kidding me! This blows, it could have been so much better."
