Loosely inspired by one of Philip K. Dick's stories, this is a superb sci-fi action thriller set in a dystopic 2084 about a construction worker named Quaid who decides to go on a 'vacation' by having memories of a secret agent fantasy implanted into his brain, only for things to go horribly awry...or maybe not.
Despite a few silly and cheesy moments, this is a wonderful, if violent action thriller that is both entertaining, and rather thought provoking. It really toys with that oft-used concept of blurring the line between what's real and what isn't, and this is one of the few films that actually does it quite well, with enough evidence to support multiple theories, with the true ending of the film dependent upon each viewer's own opinion.
Like many of Verhoeven's American films, it's got a lot of violence, but provides a lot of thought provoking ideas and material, often satirical, as well. It's all presented with some groundbreaking special effects (almost all of them done practically or in camera as opposed to CGI), a terrific score by Jerry Goldsmith, and some decent, if sometimes silly, but still fun performances. And let's not forget about the most memorable thing this film has to offer: a three-breasted mutant prostitute!
Definitely give this one a watch. It's not flawless, but it is remarkably strong, and easily one of both Verhoeven and Schwarzenegger's best films.
