I like that they showed the President being very reluctant to use nukes. I'm curious about that mad scientist guy who turned up at the end. I've been wanting to see the government prove itself useful somehow, rather than Heroman being humanity's only hope (in which case I think Earth is screwed at the rate they're going), so I hope he has something up his sleeve.
Also, I'm calling it right now-- the boss alien is Joey's father!!!!!!
