Query: Cussler Not At His Best

It seems that Cussler has faltered with Atlantis Found and has given a plot that seems to Indiana Jonesish with a new history of the world. Cussler's high points were reached with Cyclops and Inca Gold, but this one seems to drop down. While I did like Flood Tide and others in the series, this one was just like a history lesson and wasn't as good as other books of his I'd read. The beginning seemed like a copy off of Inca Gold, with Dirk Pitt saving scientist's from a temple and later realizes a clue that leads him to the villain.
