In 95% of the cases my personal score is similar to that of IMDB. But not this one ... I actually tried to watch it once again, thinking there should be a correlation to the high score, and I just miss something. I survived 1 hour. It's an average drama, pretentious, boring, and chaotic. Too many switches between past-present-future. The characters are shallow, with bad personality. The really disappointing point is that it is a bad Sci-fi. In a Sci-fi film, I expect the director to make some effort to create an "atmosphere" of the future, or of alien biology environment different from ours (e.g., as in Avatar or Arrival). But everything in this film from 2004 makes you feel like you are in the 70's: the train station, the car, house, office, and the old laptop that is somehow used for a very advanced operation - manipulating our memories. Kubrick's Space Odyssey from 68 still looks authentic, but this film from 2004 takes you 30 years back. The film raises some interesting questions, but the plot is poor and it's badly directed. Still, some people seem to enjoy it, I just don't know why. If you want a good Sci-fi drama, watch Gattaca.
