Is there a special cohort of people who just rate bomb anything not Disney? Because the IMDb rating for this film is criminal. If you want a truly sci-fi movie, Vesper is it. It has good acting, subtle but very good effects, a future world that feels both plausible and completely alien, but most of all: a story! Characters act according with their surroundings and situation and develop during the story, things happen for a reason, there are no McGuffins, Red Herrings, gratuitous action or sex or jump scares. It's something that can affect you emotionally and intellectually as well.

I had no idea what gem this film was until I finally decided to watch it. And I blame this visionless anonymous mob for complaining about the wrong things. It's not that smart a film that people wouldn't get it, it's not complicated in plot or characterization, there are no obvious continuity errors or bad acting. It has great production value. The only reason why someone would think it's not a good movie is because they felt something that they didn't expect to feel. And that's the hallmark of good art.

Bottom line: if you like sci-fi, this is a must see.
