Great movie for fathers Day, full of dad jokes.
I felt it was a cross between The Mummy with an educated woman that is not being accepted by her peers and a bubbling brother as the comic relief. They stumble across a guide who she falls for and he wins the trust of the brother.
Crossed with The Priates of the Caribbean with the Spanish conquistadores being that of the undead and taking on characteristic of the jungle.
All in all a fun movie to watch over and over.
