Example Input: This movie is about nothing but nudity and sex scenes! In the first hour or so there is hardly any dialogue... just a nude scene after another. The only main dailogue is "Take off your cloth." And personally I don't consider this as a dialogue either.I didn't see the love story in this movie... no honest expressions. Just a man who lives a play boy life. I found this movie very boring and I even had to forward many of the sex scenes that I couldn't stand any further!Maybe if this movie had a dialogue, it would have made sense! Maybe if it was shorter! Maybe if there was less sex scenese! Maybe if there was a better (senseful) ending..!
Example Output: Negative
