The Avengers is about good guys fighting bad guys. Loki is the bad guy who brings an alien army to attack earth.
At the beginning, Black Widow is captured and Loki attacks the underground station and hypnotises Hawkeye with his power.
Black Widow gets the Hulk to come to Nick Fury’s ship where Nick Fury brings the Avengers together. Black Widow fights Hawkeye and brings him back.
Loki escapes and brings his alien army to earth and all of the Avengers battle a whole army of aliens and sea monsters who can fly. Loki tries to hypnotise Iron Man but he can’t because Iron man has a robotic heart.
In Stark tower, Hulk smashes Loki like a basketball. Iron Man saves the earth by exploding a bomb in the alien spaceship.
It was a long movie and little kids would be scared, but a big kid like me would give it 5 stars.
