I really liked it, beyond the science in it being a lot more accurate than the average Hollywood film, it has a lot to offer from the artistic perspective.

However, I also felt like the more "spiritual" part suddenly took over halfway and then we were left wandering in this weird limbo that requires a big suspension of disbelief to ease the sense of implausibility. Still, I think it was an original effort to merge both science and metaphysical themes.
