Although I do give consideration to whether I'm prepared to invest the time in a very long book, it's not that the long length bothers be. If the book seems to be of interest to me, I really look forward to when I'll get the time to delve into it, with the expectation that a rich and complete immersive experience awaits me. ("The Stand" and "11/22/63" come to mind...maybe I need to add "The Dome" to my reading list.")

On the contrary, I'm put off by too-short novels. It makes me feel like I may get slighted in content. Not in sheer quantity, but in the fear that there isn't enough space to deliver a well-built world, deep plot twists, believable characters, adequate back-story and satisfying resolutions, etc.

Which is a little odd, because the short story is probably my favorite form of fiction.
I have different expectations and wants from a short story. A good short story should know it's a short story, and not be just a poorly-fleshed out novel attempt, or be a short story masquerading a novel.
