Cute story: I post that last comment where I say I don't know anything about the movie, I shut off my computer, walk out of my room and my roommate immediately says, "Hey, wanna go see a movie? We're going to see Children of Men!"
I enjoyed it -- it was almost really good. The premise and the ideas in it are really interesting, but there were a few too many explosions and a few too many cliche, predictable moments. [spoiler]The Loveable Hippy Man dies.[/spoiler] I feel like I shouldn't have spoilered that because it's obvious it will happen right from the start, even though it's presented as a huge plot twist. Every time I hear the line [spoiler]"We're safe now. We're safe."[/spoiler] spoken like it's the most profound thing in the world I want to throw things at the screen. It was a movie that would have been more effective without a clear bad guy, since the themes were more complex and more interesting than good vs. bad.
I thought the direction was amazing though. I loved that none of the main characters ever had weapons. It added a lot of tension to the otherwise long explosion/shootout scenes. I've never seen a car chase that made me feel like I was in the car being shot at quite like that before. There was a bit too much violence and it distracted from the less conventional parts of the movie, but it was done really well.
It was frustrating how close it came to being an amazing movie. Definitely worth seeing.
Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words- "mank" and "ind". What do these words mean? It's a mystery, and that's why so is mankind.
