Usually a zesty description of what happens in the first 10-20 minutes of the film is enough to let the reader know what is at stake in the story. Only when a film is morally reprehensible should a viewer give away the ending, preferably in the lead. For advance reviews, the challenge is to show the audience something without giving awayall the plot points. Because a review should be illuminating, it is better to give away a bit too much than to be so vague that the reader gains nothing from your review.
