HARRY POTTER AND THE
HALF-BLOOD PRINCE

Hello. I'm this series' recurring wild card character. Am I good or am I evil? You don't quite know yet. I'll open this film by making a mysterious pact with the villains, for reasons which will, suspensefully, not yet be revealed.
This film called for a dark, gothic female character who is dressed in black lace and gothic and stuff. For some strange reason, they cast me, Helena Bonham Carter. It must be my amazing range as an actress. It is I with whom Alan Rickman makes his mysterious pact. I bet you want to know why!
Wow, such suspense! Now for two hours of nothing but my efforts to hook up with the annoying redhead kid.
  TWO HOURS LATER
Oh shit, we're running out of time!! Time to start thinking about plot development. Okay, Harry Potter, listen up. I need you to make Jim Broadbent tell you how to defeat Voldemort.
All right. Hey Jim, why don't you go ahead and tell us? After all, you really have no reason to withhold that information.
Never!
Fine. I will solve this problem, as usual, by using a deus ex machin- I mean, a magic spell.
Well, okay. Voldemort has put his soul into some shit and hidden it somewhere, so to destroy him you have to find the magical artifact.
Thanks. Hey Dumbledore, Voldemort has put his soul into-
Yeah I know. And I know exactly where the artifact is. Follow me to a cave now.
Ok.
Be careful! Voldemort has protected his magical artifacts with magical traps. We have to tread carefully because magic.
INEXPLICABLE ZOMBIE ATTACK!
Quick, Dumbledore, use MAGIC!
Success! Oh wait, the artifact was a fake. Which means that the only actual thing that happens in this film was all for nothing.
And now, I will murder Dumbledore.
Wait.... why?
I don't remember. It's been so long since the beginning of the film that I've forgotten my motivation. In any event, ABRACADABRA!
NOOOOOO!!!! Dumbledore!!! Why didn't you defend yourself using MAGIC?
Yeah, I probably should have thought of that.
Wait a second, who is the "half-blood prince" mentioned in the title of the film?
I am.
You say that as though it's some massive revelation, but absolutely no weight has been placed on this particular mystery. I mean, what does that even mean?
Well, you see- Oh dear! We're out of time. Looks like you'll have to wait yet another year in the hope that this plot will advance one inch since 2003.
This is yet another film of nothing but unsubstantial filler! And yet, we're trillionaires!
