Straw Dogs Review
I originally rented Straw Dogs because I heard the main character (played by Dustin Hoffman) was a mathematician. Disappointingly, the point of him being a mathematician is to show how wimpy he is. When a drunken Irish mob pushes him to the edge, he transforms into a raging sadist. The director passed up a good opportunity to have the character use math to defend his home against the mob.

This mob is actually trying to lynch a local retarded murderer who's hiding out in the house. Wanting him to have a fair trial, Dustin Hoffman responds by killing the entire mob with crude makeshift weapons. It wasn't very clear, but I think he's also trying to protect his wife from being raped although she was raped twice earlier that day (this rape scene lasted forever and worst of all I was watching this movie with my parents), molested later by the retarded man and finally slapped around by Dustin Hoffman. My Mom was terrified by the scene when the local exterminator throws rats into the window and shouts, "I don't just catch them. I breed them too!"

P.S. Although his character claims to be an astromathematician, the equations on his chalkboard are clearly mechanics formulas.
