This is a B-movie that is for sure and at certain points it also borders very soft core porno.
The plot is very thin and very simple. The action and effect are overdone, the dialogue is from acceptable to lame and the acting is worse.
My guess is that the main focus for this movie has been the focus on showing of the beautiful women's attributes (i.e. boobs, butts, legs, face etc.) in almost any situation available.
It is a B-movie, it is not good, but the women makes it just worth the watch.
