As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.

Ex Output:
Negative

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..!

Ex Output:
Negative

The first movie in the series is good, but, Road Warrior is better. but does that mean it`s bad? Heck no! This is actually one of the best of the sci-fi genre.It`s about this guy named Max, (duh!) who gets pissed at this motorcycle gang for killing his friend and family and seeks his hellish revenge.

Ex Output:

Positive
