Say what you will about the movie, but the world building is amazing
I do recall that the movie didn't quite work for me the first time I watched it - I rated it a six at the time. Passing grade, but flawed. But I've since had reason to watch it again, and then again, and damn. You need to watch this several times, and really pay attention, to start to unpack it all. It feels like it's been adapted from a novel, or a series of novels. There's too rich a universe here for just one movie, and I think that may have been the reason why it somewhat failed as a single movie: too much to take in all at once.
The thing is, though, this is a great universe to play around in, and there should be more. Movies, or comic books maybe. Something. It would be a tragic waste if this world were entirely abandoned.
