The Checklist

1. Hopefully made between the late 70's and early 90's

2. Runs about 90 minutes long.  
3. Should observe the 10 minute rule, meaning something should happen every 10 minutes or so. That something being an explosion, car chase, gunfight, monster attack etc. In a pinch, some crazy dialog or character antics will do  
4. Slow motion is always a good thing - especially explosions - nice fiery dangerous ones  
5. It's ok (encouraged) to rip off the classics: Rambo, Predator, Robocop, Die Hard, Dawn of the Dead, Alien, Jaws, Road Warrior, Halloween etc 
6. It's better to be unintentionally funny than campy. Be sincere.
