I hated that movie the first to I saw it. I was bored with it. Now I love it. I really enjoy how much time they spend establishing the atmosphere and characters. It all feels very real and has depth. I loath the speedy sci fi that tries to touch on atmosphere and then hurries along with their paper characters and so on. So much sci fi I encounter now feels little more than a long trailer with no idea how to end.
The first time, a bunch is quite confusing.
