Your choices are:
- the Alien series (I'm not going to use that "word")
- the Predator series
- the Terminator series.
You can only choose one. As an additional talking point, I'll allow you to briefly discuss your favourite film from your chosen series.
Mine: the Alien series, Aliens is the best. My reasoning?
"Hey Vasquez, anyone ever mistaken you for a man?"
