There Will Definitely be Blood Maybe

You stand next to your kid on the sidewalk near the movie theater. You had agreed to take him there for his birthday, as he had always wanted to see Happy Feet.
But you read the sign, and it says "THERE WILL DEFINITELY BE BLOOD MAYBE". You ask yourself "Can I really show this to my eight year old son?" You were unsure about the movie. There was no rating, and the confusing title made you wonder if it was a horror movie or just a family friendly comedy.
"Daddy, let's go see that one!" Your son says, pointing to the sign. You can't disappoint your son, at least not again. The theater's name, "Y CINEMA" swirls around in your head as you resist the urge to scream. You are filled with terror. Your son begins to cry, feeling that you had disappointed him once again. You begin to sweat nervously, terrified of what's to come. "Is there blood," you think, "And if there is, is it definitely there? Or only maybe?"
Your son begins to walk back to the car. He is crying for the Y Cinema. He no longer cares about Happy Feet, he just wants a better parent. But you remain determined to give him the entertainment not that he deserves, but he needs. You grab his hand and begin to walk into the movie theater, when you realize the advertisement art for the only movie they are showing.
It displays a typical horror movie setting. The killer wields a butcher's knife, while the victim screams in terror, much like you feel like doing due to your child's deprivation of happiness. However, there was no blood. Only the words "definitely" and "maybe", which were flashing violently inside of your head. You can't handle it anymore. You fall to your knees and begin to scream. Your child is in the corner of the theater in a ball, weeping softly to himself.
He is dying of boredom.
Dying.
