I accept your criticism for not watching all of the film, but let me push back on "worthless." As you might see in other comments, a lot of people who did watch the entire film agreed with me.
I don't pretend to be a professional movie critic (most of my writing is on politics and photography), but I don't think you need a PHd in cinematography or film studies to offer an opinion on a film.
In any case, thank you for reading the review. Many readers agree with you that I should have watched the whole film.
