So let's all make the most successful film of all time. What plot points, special effects, or characters are not original, are not clever, but instead are tried and true methods to appeal to dumb masses?

I'm thinking of the following:

Story must have lots of explosions. Explosions must always be in slow motion. Someone should always walk away from said explosions, but must be too cool to look back and observe the damage done.

Characters should always include a nerd, a black guy, a tough girl (not love interest), another girl who always manages to catch the wind in her hair and orders the nerd around, and an arrogant white hero.

Gravity need not be consistent or cooperative.

Any additions?
