Just so no one spends 42 minutes of their day, the videos mostly consist of building the set. They're not really reviews, more so as showcases of the sets. The temple is filled to the brim with traps cleverly hidden away, and Destiny's Bounty has a lot of hidden compartments and generous amounts of space for minifigs.
EDIT: From what I've found, these sets are sets found early in stores lucky enough to receive them. Brickvault has gotten ahold of some of the Ninjago Movie sets. Here's their video on the Green Ninja Mech Dragon.
