I feel like the 'weakest link' award went to Zoe Saldana- who I generally like, but who seems to allow the 'strong woman' thing to disintegrate whenever the plot calls for it.

Do you know this cartoon? It's called "The Real Guardians of the Galaxy"

The Centauri, with their funny hair, Napolionesq mannerism, and nine tentacle penises started out in season 1 of Babylon 5 as harmless comic relief, and with the Narn being the dodgy potential bad guys. By season 4, the table was so turned, the Centauri was no longer a laughing matter, and we all wanted to hug a Narn…

Zombie Survival Guide (mostly a parody, with a mildly serious tone to it), then World War Z (a really serious fake oral history of the zombie war), and then "Recorded Attacks" (graphic novel form of the history section of the survival guide, which just sort of stripped away the whole "Funny haha" part).

I was going to finish reading, but...bored now.

EASY (Well, not always serious)

This started out as a comment on super seriousness of the comics of the time and steadily got more ridiculous over time. I guess that's the reverse answer to your question tho.

The Trio from Buffy. At first it was all fun and games, and then came the attempted rape, the shootings, the flaying...and so on.

"He came riding out of the East…"

When I first saw Dalek, I finally understood why they were so feared. But by Eleven's run-ins with them, I was like "meh."

Yeah, but Jack Burton DOES kill the main bad guy. That's not usually sidekick territory.

Wait... It didn't help. I still don't understand why Clark was a lazy bastard for the first 30 years of his life besides both his dads were assholes.

I laughed maybe twice over the course of the 90 minutes and thought someone was pulling my leg with that "ending". No explaining in the world would have changed that. But then I simply watched it again a few years later, and laughed more. And then again, and again. So funny :)

River's favorite word: Spoilers. I think the way that they wrote this twist out was amazing, although I know it's a controversial topic in the fandom. The Doctor's enemies kidnapping and further genetically altering the child of two of the Doctor's companions to raise her to be the only one that can kill him, only to…

Cabin in the Woods. The last scene where the predictable plot gets smashed into pieces and the entire planet gets destroyed? Brilliant, especially for a movie that already subverts the expected plot the entire way through.

Just because it's gonna piss some people off, I'm gonna say this one:

Not necessarily a plot twist, but (in my opinion) one of the most brilliant plot resolutions ever. I've consistently witnessed first-time viewers burst out laughing with joy at how clever it was.

I remember having a lot of fun with this one on DVD, going back to check the clues.

Empire Strikes Back of course

When will henchmen stop falling for that old trick?
