Mmm, Blade Runner-y. (spoilers)
So the comparisons to Blade Runner are pretty prevalent from the start: lingering shots of night skylines, the synthesizer score that clearly emulates Vangelis, and dark lofty rooms with light shining in through the windows. It pretty much ends there, though.
The movie itself is kind of confusing and slow-going. Eventually time starts to repeat itself and the main character ends up having to dodge his past self while basically re-enacting everything that came before from a different point of view. I was pretty much lost at the end though...they didn't do a great job of wrapping everything up. My guess is that he eventually found another wormhole (through time repeating itself over and over in that sequence, until he finally catches up with one of those "alternate" dimensions) and then he meets up with the girl in the end (at some indeterminate time in the future). But all the stuff she was writing in her notebook, her "novella" or whatever, was very confusing. It almost makes it seem like the whole movie was basically just the story she was writing. What are other people's thoughts?
