Very nice sequel of independence day 1 very nicely enhance the old story by showing aliens conspiracy against earth. And the alien ship this time is really very very big that is around 4500 kms in diameter that it stick to half of the earth that is a nice seen when it landed on earth with its own gravity which destroy the whole world.
Sci-fi content is also new here such as high speed space vehicle through which they travel between earth to moon in few hours.
One good twist is there that there are some other alien spicies which are used to help us and they are danger for our enemy aliens too. That the friendly aliens have some thing which destroy their planet and then they come to earth and we use to save one of them and defeat those enemy aleins.
Old character , in this movie alos they played a nice role and they are shown the one who can feel those aliens because they use fight with them earlier.
Overall movie is awesome , it is one of the finest movie sequel full of action must watch it.
