I Am Number Four 

I am Number Four is the straight up worst name choice for a movie because obviously I am Number Three would have made so much more sense. Because 3 is a number coming after 2, but not overshadowing it. Also a number coming directly before 4 but refussing to be bullied or made feel less than by it. Strong number, yet emotionally sensative. In other words a number that knows its place.

Dude, that movie choice was SUCHHH a I am Number Four Choice
