I'm not quite sure what Wong was gunning for here, but there's a bit of Terminator and Iron Man in Future X-Cops. Wring it through a Hong Kong filter, mix it with Wong's trademark sloppy comedy and you get a film that's too cheap to be a blockbuster, but silly enough to be entertaining.
Andy Lau warps back from the year 2085 by accident. Once here he needs to find a way back to his own time, in the meantime he helps out a female officer in her quest to beat an international crime syndicate. But don't worry too much about the plot, it's just an excuse for some silly fun.
And silly fun you're going to get, that is if you can see through some of the shadier parts of the film. The special effects for one are absolutely atrocious, at the same time they also have a kooky charm that goes well with Wong's overall approach. Not Wong's best film, but it made me laugh out loud more than once.
