The latest hybrid-release blockbuster is a summer adventure flick that looks like it was adapted from a roller coaster at Disney World. With Dwayne Johnson and Emily Blunt helming the cast, the story follows a British doctor (Blunt) on a mission to uncover an ancient Amazonian tree with unparalleled healing abilities. In order to track it down, she enlists the help of a wise-cracking skipper (Johnson) to take her down the river in his ramshackle boat. An epic journey and lots of PG-grade flirting ensues.
