The movie takes place in a world where everything is bright green for some reason.

Is there much here in the way of dialogue or plot spoilers? No, actually, almost none at all. Is this basically just a montage of attractive people talking to each other and acting out imaginary stuff with CGI beings who will be added later? Yes, that's pretty much the entire thing. Did I watch it anyway because I'm a huge nerd with a crush an all these characters and actors? Do you even have to ask?
