We got following genres mixed:
Action, Space, Sci-Fi, Romance, Mecha, Military, Horror and if you want Psychology; (AND definitely DYSTOPIA!!)
Our main male protagonist: From zero to hero to asshole and then back to hero!
Our main female protagonist: From asshole to heroine!
Our main antagonists: From easy level 1 monsters (even if they encountered the whole earth and are a real thread) to more advanced level 10 jerks!
Our settings: Earth crowded with monsters and some survivors in really, really bad shape and a space station with hardcore (cause military) hierarchy and a quite sterile feeling (with human monsters; at first!)
Movies that are mixed: Starship Troopers, Resident Evil (sorry, no Zombies), Black Hawk Down, Mutiny on the Bounty, etc.
EXTRA: Real feelings (Yes we have a love story!), real suspense, quite real human decisions (Very rare!)
Damn it; Why is the rating for this so low!!!
