To write a review to a good movie is to talk about why and how its good and persuade the readers to go and see the movie. Talk about the problems that the characters go through and how they solve it but don't give out the entire movie or else it'll be a huge spoiler and the readers won't be interested.
So to keep the answer short explain why and how its good and presaude the readers to go and see it like "you should go and see it because..." And list your reasonings.
Hope this helped :)
Have a great day
