Terry Gilliam's and David Peoples' teamed up to create one of the most intelligent and creative science fiction movies of the '90's. People's proved a screenplay with bizarre twists and fantastic ideas about the nature of time  I especially love the idea one can't change the past; it's a nice counterpoint to so many time-travelling movies which say otherwise  biological holocausts and the thin line between sanity and madness. Gilliam visualized his ideas with unique quirkiness, perfection and originality.
The story itself is engaging: one man, James Cole (played by Bruce Willis in a heart-warming performance) travels several decades to the past to retrieve information about a virus that's wiped out mankind and left only a few survivors alive living underground: with the information he'll collect, scientists hope to find a cure so everyone in the future can return to the surface. But because their time-travelling technology isn't perfect, he ends up being sent towards different other pasts and complicating things. And from that a brilliant science fiction thriller with shades of film noir ensues as the multiple pieces of a huge jigsaw start fitting together to form a bizarre narrative involving animal right activists, end of the millennium paranoia, biological weapons, the perception of reality, and the definition of sanity. With such a complex movie, it was easy for Gilliam and Peoples to create a mess, but instead Twelve Monkeys is a thought-provoking narrative which will please those who like to be challenged and have patience to appreciate some crazy ideas.
I watched this movie once around 10 years ago. It marked me a lot: I remember still thinking about many days after-wards; for my young mind this seemed quite mind-blowing and it was one of the first movies to make me appreciate cinema as something serious and important. I've re-watched this movie a few days ago on DVD and it's better than I remembered it. Brad Pitt still steals all the scenes he's in, playing Jeffrey Goines  almost a prelude to his Tyler Durden character in Fight Club  a rich kid with some anarchist/non-conformist ideas who's also crazy and, according to Cole, perhaps responsible for the virus. The scenes between Jeffrey and Cole in the madhouse are the best in the movie, Pitt's eyes, voice and quirky mannerisms convince you he's really a crazy guy locked in a warped logic only he understands. Pitt's Oscar nomination was well deserved! Surprising was also Bruce Willis' performance: his I didn't remember very well, but it's beautiful and full of sensibility; he plays a man who spent almost all his life underground, and when he comes to the past you'll share his childish fascination with something as simple as breathing the fresh air of the morning or watching the sun go up. Cole is a rather ambiguous character, Peoples' tried to imbue some darkness in him, and he does other disturbing things to other people and to himself: the scene where he removes his own teeth reveals how far his dementia has gone unchecked. Ironically Cole didn't start as a crazy character, but when he starts warning everyone about the end of the world, he's considered mad and convinced it's all in his mind, until he arrives at a point when he can't distinguish past from future, reality from fiction. Willis spends a lot of time looking confused and insecure, and it works perfectly. One of the fun twists in the narrative is when Cole's shrink, Dr. Kathryn Railly, finds undeniable proof he's really from the future and now has to convince him again of his mission to save the world. The screenplay is full with weird twists like this and it keeps the movie in a fast pace. Their relationship is also well-handed, although perhaps a bit compressed for time's sake. But I enjoyed watching Cole and Railly falling in love and trying to escape the authority of the future to live a peaceful life in the past. But then things end in a tragic/bittersweet climax at an airport, wrapping all the pieces together, which will blow many minds away.
There are two great endings in this movie, a twist in the sense of Se7en or Fight Club, and a more intimate ending where Railly is crouching next to Cole who's just been shot and looking around for a younger James Cole who's witnessing his future self die; the two share a brief look, and she smiles at him. The twist is brilliant, but I prefer this ending for emotional impact. Madeleine Stowe is very good playing Dr. Railly, she drew many different emotions from me in her performance. The movie is filled with a sense of fatalism with the idea the past can't be changed: this movie shows that in a terrifying way. It reminds me of Chinatown in that sense, the way Jake Gittes messes everything up the more he tries to help. Railly's character shares that fatalism, the more she tries to help Cole  first dealing with his 'madness' then helping him in his mission  the more they're sucked into tragedy.
The twist ends with a hopeful note, though, with the feeling Cole's mission hasn't been in vain. Twelve Monkeys is a great movie to watch if one wants to be entertained; it's not supposed to be art, although it's more artists than many artistic movies. It's an unpretentious movie where all elements, from music to editing to costume design, etc., came together beautifully to produce a modern cinema masterpiece.

Sure I've seen bad movies in my life, but this one was so bad that I actually became angry in the theater. I wanted my money back. I wrote to the director asking him to refund my movie ticket, of course I didn't receive a refund (or even a reply) but it's the point that matters. On a scale of 1-10 I give this movie a -42. Why did the "Jeep" (Chevy Blazer??) stop running from being hit with a bat? Why did they hit the "Jeep"(Chevy Blazer?????) with the bat in the first place instead of cracking the bum's skull? The plot was thin, the movie filled with obvious clichés, and certain parts of it just didn't make any sense.
