"I'd rather chase the sun that wait for it." (I am the Messenger, Markus Zusak) Don't read too much into it. There is no depth, no concealed abyss. What you see is what you get. Let's leave it at that.
I really really love Tony Stark.
Iron Man 2, a little less. But it was engaging and fun and better than most comic book movies (especially since it’s a sequel). Watch it!
