Your reply is pseudo-intellectual snobbishness and of no defense. Others have made the same point without giving away the ending. You are of the ilk that gleefully goes around telling others the ending of movies so others will think you are in the know. It makes one feel important and that you know something others don't. Most are through with that after high school.
Reviewers accomplish the same thing, but they don't feel a need to give away the ending. They have the ability to communicate without resorting to ruining the movie for others. Yes, you have ruined the movie for me.
