Hi Manuel,
There are quite a few corrections for the spelling and sentence structure, but the most important are as follows;
1) In a film review when you discuss the plot you usually do so in the present simple tense. So for instance "about a young girl who is on vacation" or "Baby is a good student and she plans to go to university to study economics".
2) It's not a good idea in a film review to tell the reader the ending of the film, because then they have less reason to watch it. It's better to concentrate on what you like or didn't like and the reasons why.
I presume someone will help you with the specific corrections, but that's my input at this stage. I hope it's helpful to you.
Best of luck
Andrew
