I agree with Darren’s summary. The film’s strength is its visuals, which are great - big, sweeping space stations and ships and battles and explosions and harpoons and robots and so on. Everything else - meh.
Not only did it take too long to get anywhere but everything about it was haphazard and incoherent. The bad guy was “generic evil corporate type #3” (and did we find out what his weird condition was? I may have zoned out at that point), there were a raft of secondary characters who barely registered (apart from the French guy but including the entire rebel group) and the ending was literally deus ex machina. And the bit after the ending was…embarrassingly emotionally manipulative and soppy, as if Hallmark had decided to venture into sci-fi.
I came away thinking that the creators really wanted to make a mashup of Cowboy Bebop and The Fifth Element and instead they made…this.
I had the subs on the whole time. Weirdly, some of the phrases that were neither in English nor Korean were labelled with the wrong language for some reason.
