Must-see movies are futuristic classics that shouldn't be missed. Of course, not every must-see is perfect. That's why we've rated them 1-5 on the patented "crunchy goodness" scale.

Title: Westworld
Date: 1973

Vitals: Based on a script by director Michael Crichton, Westworld is the tale of an "old west" style amusement park gone awry when the androids populating it start to defy their human masters. Nerdy vacationers must figure out what's caused the cowboy and hooker bots to start killing instead of being killed.

Famous names: Michael Crichton, Yul Brynner, Richard Benjamin, James Brolin, Majel Barrett

Crunchy goodness: 2

Ripoff: Two decades later, with better special effects and a better director at the helm, writer Crichton ripped himself off with Jurassic Park, another tale of an amusement park gone terribly wrong. Apparently CGI raptors make more compelling bad guys than Yul Brynner's cowboy bot.

Life lesson: The robots will rise up and kill you. How many times do we have to tell you that before you LISTEN?

Stunt casting: Yul Brynner, AKA Hottie McHotterson of the 1960s, played countless cowboys in Western flicks in a rather robotic manner - casting him here as a robot cowboy is both satiric and appropos.
