Westworld (1973)

A robot malfunction creates havoc and terror for unsuspecting vacationers at a futuristic, adult-themed amusement park.

Simple, but effective sci-fi thriller with a decidedly anti-consumerist and skeptical stance concerning future development.

Halliwell**: "Unusual and amusing but under-produced melodrama with slipshod story development and continuity, atoned for by memorable moments and underlying excitement."

Maltin***: "Engaging story..."

Michael Weldon/Psychotronic: "Yul Brynner is great in a silent role...Richard Benjamin and James Brolin aren't so great in speaking roles..."

Spaceballs (1987)

Planet Spaceballs' President Skroob sends Lord Dark Helmet to steal planet Druidia's abundant supply of air to replenish their own, and only Lone Starr can stop them.

Hit-and-miss sci-fi spoof is for the most time simply silly, the more successful sequences are the ones directly parodying popular sci-fi movie scenes.

Halliwell (no star): "Flabby spoof of Star Wars, without any funny ideas."

Maltin**1/2: "Likably silly parody of STAR WARS (years after the fact) is basically a collection of jokes, both verbal and visual. Enough of them are funny to make for pleasant, if not hilarious, fun. Surprisingly innocuous for Brooks and Co..."
