Before "Star Wars," George Lucas had another vision of the future, particularly in a long time from now in a galaxy that happens to be our own. "THX 1138" is his Distopia film, his "1984" or "Brave New World." It's directly inspired from those works, borrowing the ideas of drugs to sedate human emotion (Brave New World) and sex being illegal (1984). It's a visionary work, not a revolutionary one, but for the early 70s, it impresses. Lucas manages to bring his concept to life, even if it's not exactly as thrilling or interesting as what the Star Wars saga would be.
THX 1139 (Robert Duvall) is an ideal member of this "utopian" community where religion means stay calm and do as you're told. When his roommate, LUH, begins to change out his sedatives with other pills, he begins to fall in love with her. Consequently, the "big brother" equivalent finds out, and THX is taken captive.
"THX" can be boring at times. Though you can tell Lucas has put a lot of thought into this world, he doesn't care to offer any help to those struggling to make sense of it. There is no clarification dialogue -- you have to pay close attention to the images and surroundings to understand it. This is admirable, but makes things difficult for most viewers. The film therefore drags at points not necessarily because what's going on isn't interesting, but the viewer is missing contextual help to illuminate the action on screen.
Fans of the genre will appreciate Lucas' contribution and his imagination, but probably not love it. The themes are light and the drama low. There's no sense of danger or incredibly sympathy for the main characters. One thing to note is not to watch the Special Edition. As Lucas loves to do, the SE goes back and adds CGI to the film, which is a travesty. Part of what makes these movies so great is that they offer a vision of the future from the perspective of 30 years ago and today's technology doesn't interfere. Do your best to get a non-remastered copy.
