Right now, there is no specific guidelines as to how one must write the review. I always think that we should reveal the plot but not to give the audience the ending so that it will arouse an interest for them to get to the movie right away. That's what I did to the movie PK. You can take a look at the people's responses. https://www.triplea.reviews/aaa/@rosatravels/aaa-come-and-watch-pk
