You see tenderness I see a chance to use my flamethrower

Monsters (2010 film) Spoiler Ahoy!

Andrew and Samantha phone their families. As they finish their calls, an alien appears at the gas station, but it turns out there are in fact  two aliens who are communicating with each other - rather than being monstrous, the giant creatures display tenderness, even beauty.

I didn't see beauty.  I saw a perfect chance to napalm critters who are groping tentacles.

Just call me a xenophobe.  Humanity uber alles!
