Somebody help me : )

This is my essay. please correct this one. Thank you so much

Have you ever heard about movie, World Invasion?
This movie deals with Invasion of plain Aliens. The story of this is slightly sloppy.
That means component of it is simple. Let me show you Best points and Bad points of it.
Before, you have to know the outline of his movie
; The human are invas-ed by aliens in all over the world, involving L.A.
Fortunately, The Marine get order to protect civilian without serious damage and fight and go to fight
against them at shore.
Unforunately,they already fire at civilian.
so many people of L.A are injured or died.
They have to embark on counterattack.
Shortly after, the preliminary troop fight against Aliens.
Each of soldiers get order in charge of their role.
It may be the way to exacerbate situation. Because at first, Aliens beat
soldier ahead of them. They are ebullient but know nothing about Aliens,
so they lose on and on.s a result, Many civilian and even soldier
become the sacrificial of the battle.
However they beat Aliens one way or another.
That's it.
What do you think about it? There are nothing to be amused or fasciated.
If you already watch this, y'all may agree with me.
It's because story is sloppy. The spectacle of battle scene is pretty cool, but that's it. There is no change of backgroung and tension like movies
such as "WORLD WAR Z" or " War of the Worlds". It frustrate people.
Solemnly, It's really unintersting. the movie consist of bullet,gun and battle.
It's not sassy. It's the case!!
But It is really touching. that's true. Most of all, I am really sad and sorry
for our soldier. They sacrifice theirselves to contribute to their country,
I think most of students don't think of them, let alone respecting them.
It's highly rude, sassy, impertinent and shameless for students not to thanks for them.
To remenber them is foremost is known but most often, they don't realize how holy they are.
It's temporal at Memorial Day ans Veterans Day.
You guys please. Please BE thankful for soldier who died for us and our country.
End

Thank you, teacher
