Death Race 2000
Just a classic cult movie, my dad told me it was really good, and he was right, its basically a comedy which kind of has a political message too it, although the message might be a little outdated, as I think its more about how society was doomed in the 70s if things didn't change.
The plot is fairly simple, it centres around the national sport, which is a trans-continental road race, where you pick up points by killing people, getting varied points for different people you kill, leading to some comic moments such as "Euthanasia" day at the hospital on the path of the racers.
Its the kind of film you really have to see to decide whether you like it or not, words don't do it justice
I love it purely because its a dark comedy which is fairly satirical at the same time, and is well worth checking out
