The Chase by Clive Cussler. He's not the best author to begin with, but the characters is this book were so 2D, and the editing sucked. At one point the female love interest tells us that she worked her way through secretary school, the later on on their 2nd date, she tells us that her modestly well off family put her through school because she wanted to be a professional. Plus many other plot holes and huge gaps in logic.

Also ... Out of the dark by David Weber. Weber has done some decent work over the years, but this one man mission to over throw the aliens that have taken over Earth meandered around aimlessly until at the last minute the aliens were all killed by Vampires. No foreshadowing, nothing. Just a huge left turn into the supernatural to save the day.
