Allbthe actors have played the marvel characters very well. The cornel unites all the characters for noble cause that is to save the earth from loki.
He unites the Hulk, Iron Man, Captain America and whn they get hold of loki in the start Thor enter the movie.
The movie is so interesting that you dont feel like moving your eyes away from the screen.
All the characters have done the action scene very well.
The story goes on when loki after getting captured plays mind games with the Avengers and makes them apart. Attacks their ship. And then one by one these avengers come together and smash all the aliens from the outside world.
