Kian Hin and sisters midnight yesterday. Overall, the movie is awesome. We have Chris Evans returning to reprise his role as Steve Rogers aka Captain America, Robert Downey Jr as the billionaire, genius, and philanthropist Tony Start aka the Iron Man, Scarlett Johannson as Agent Natasha Romanoff , Chris Hemsworth as the demi-God Thor. Pretty much most of them are from the Marvel comic movies are getting their roles.
The movie started off with S.H.I.E.L.D. Director Nick Fury arrives at a remote S.H.I.E.L.D. facility during an evacuation. The Tesseract, an energy source of unknown potential, has activated and it opens a portal through space from which the exiled Norse god Loki steps through. Loki takes the Tesseract and uses his abilities to take control of the minds of several S.H.I.E.L.D. personnel including Dr. Erik Selvig and Agent Clint Barton to aid him in his getaway. In response to the attack, Fury re-activates the Avengers Initiative - which we know from the movie stopped for some reasons - we saw Nick Fury getting Tony Stark in the group, in Iron Man 2, don't we? Agent Romanoff were sent to find Dr Bruce Banner aka Hulk in India while Agent Coulson is sent to approach Tony Stark and Fury himself approach Steve Rogers.
We all know from the Thor movie that Loki was banished from Asgard in the final scene and during his exile, Loki encountered the Chitauri, an alien race seeking to conquer the galaxy. In exchange for the Tesseract, the Chitauri agree to help Loki subjugate Earth.
Suiting up, Captain America and Iron Man travel to Germany to apprehend Loki, who is recovering iridium needed to stabilize the Tesseracts power, and demanding that the civilians kneel before him. Loki quickly surrenders when the two heroes arrive, and he is escorted back to a S.H.I.E.L.D. Helicarrier, a high-tech, flying aircraft carrier. However, Thor, Loki's half-brother and the Norse God of thunder, arrives and attempts to free Loki so he can try to reason with him on his own, but he gets into a fight with Iron Man and Captain America. If you asked me, the fight scene is awesome.
They still get Loki to the Helicarrier, and he is locked in a cell designed for Hulk. I find it funny the way Nick Fury say the ant and the boot parable. Anyway, while inside the Helicarrier, Tony Stark questioned why Fury reactivate something that the S.H.I.E.L.D. already called off previously - thus, making the team disintegrate and then as the group argue, Clint Barton and Lokis possessed agents attack the Helicarrier, disabling its engines in flight. As Stark and Rogers attempt to restart the damaged engines, Thor tries to prevent Dr. Banner from turning into the Hulk and destroying the ship from inside. While fighting Barton, Romanoff discovers that a blow to the head powerful enough to knock him unconscious is enough to break Lokis mind control. By the end of the battle, Loki escapes, Thor and Dr. Banner have been ejected from the ship and Agent Coulson is killed.
Fury uses Coulson's death to motivate Stark and Rogers to work together as a team, with Romanoff and Barton. However, when they realized Loki's plan, it was already too late as Loki open the portal to the Chitauri home world over Manhattan, summoning a Chitauri invasion using a device built by Dr. Selvig. Then the Avengers started to defend New York City from the Chitauri's invasion, but finally came to a conclusion that they will be overwhelmed.
With help from the reformed Barton, Captain America and Thor evacuate civilians while Dr. Banner transforms into the Hulk and goes after Loki, beating him into submission. Romanoff makes her way to the portal, and she hits Dr. Selvig over the head, freeing him of Lokis control. Dr. Selvig reveals that Lokis staff can be used to close the portal. In the meantime, the S.H.I.E.L.D. ordered to send a jet that will fires the nuclear missiles to end the invasion - Fury quickly informed the Avengers about that and Iron Man intercept the missile and direct it to the portal and fires the nuclear at the Chitauri's home.
The final scene have all the Avengers going separate ways and Thor escorting his brother Loki and Tesseract back to Asgard for good. I never waited for the post-credit scene, but there is a scene there, and it means we will have part 2 :D
