back to the future

This movie is very popular among many people.
I think most of people have seen this.
Of course i have seen it.
Especially,back to the future2 is one of the my best story!!

But today we watched no.1 in my class.
Doc achieved to make a time machine.
He was so heated. he showed it to Marty and explained how to work it.
Marty was getting to use it,when Terrorist came to kill Doc.
Unfortunately,Doc was shot by them.
Then they tried to kill even Marty too.
Marty got to the time machine in order to escape from them.

But regrettably he failed to escape in the attept,but he wasn't killed by them.
That is, he went to the past in spite of himself.

Besides unfortunately,he run across his past mother.
And he changed past occurrence without notice.

He needed Doc's help to go back to the future.
And they helped each other.
they did some things.
I can't tell you any more,because if you've never seen this movie, if even you know about all this story,it'll be boring, no way.

That's why you had better watch all this movies1,2,3.
