The good part though is the introduction of new characters -- Hank Azaria as an evil Pharaoh Kahmunrah perks up the screen every time he appears. His interaction with Ben especially raises laughter at almost every instance, mainly due to his vocabulary and dialogue delivery.
Also interesting are the portions featuring Alain Chabat as Napoleon Bonaparte, but the parts featuring General George Armstrong Custer (Bill Hader) are a big bore. Introduction of Al Capone (Jon Bernthal) sounds good on paper, but hardly adds to the plot. However, Albert Einstein bobble-heads are cute and would be loved by kids.
The most adorable of them all though are the three Cupids who light up the scene every time they appear.
The actor who does get a meaty part for herself is Amy Adams who enacts the role of Amelia Earhart who was the first woman to fly solo across the Atlantic Ocean.
Ultimately the film turns out to be more of a guided tour of various characters from history.
