What book have you read that the ending left you very disappointed?
I just finished reading 'Cryptonomicron', and was really into it. It took a while for me to read, but only because finding time to read it was an issue. I was floored when the ending basically wrapped up in a handful of paragraphs, and even then with a lack of detail and such an improbable manner. The entire book was sooo good on the 'hows & whys', and then it just dropped a brick on your head, telling you that it's over.
I mean really?! The great ending was to hose down the main chamber with fuel oil, light it, and melt the gold out of it? What about all the gold that would just pool on the floor, or go down another shaft? What about the jewels? And how the hell do you drill a hole sideways at a slight upward angle without needing men to go up there and work it? Why not just send men in there and claim all the gold if that was the case? And what was the deal with that crazy lawyer Andrew Leib? He seriously shows up in the jungle in a business suit and stalks the group? Ugh, so many questions.
Oh well, the rest of the book was great.
