Russell Franklin: Just what the hell did you do to those sharks?
Dr. Susan McCallister: Their brains weren't large enough to harvest sufficient amounts of the protein complex. So we violated the Harvard Compact. Jim and I used gene therapies to increase their brain mass, a larger brain means more protein. As a side effect the sharks got smarter.
Janice Higgins: You stupid bitch!
Tom Scoggins: They're big, real big.
Carter Blake: What's that?
Tom Scoggins: The size of your brass balls!
Russell Franklin: You think water moves fast? You should see ice. It moves like it has a mind. Like it knows it killed the world once and got a taste for murder. After the avalanche, it took us a week to climb out. Now, I don't know exactly when we turned on each other, but I know that seven of us survived the slide... And only five made it out. Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man.
The Parrot: Fat butt... You got a big fat butt!
Preacher: Any of your nonsense and we're gonna have tiny little drumsticks on the menu tonight.
Carter Blake: They got a pill for what's wrong with you?
Carter Blake: A 45-foot shark, and you hit me. Nice.
Preacher: Shit, it could've been worse. I could've let him eat your ass.
Preacher: Einstein's theory of relativity. Grab hold of a hot pan, second can seem like an hour. Put your hands on a hot woman, an hour can seem like a second. It's all relative.
Tom Scoggins: I spent four years at CalTech, and that's the best physics explanation I've ever heard.
Tom Scoggins: Now you see how that works? She screwed with the sharks, and now the sharks, they're screwing with us.
Dr. Susan McCallister: You wait your whole life for a single moment and then suddenly it's tomorrow.
Carter Blake: No, what you've done is taken God's oldest killing machine and given it will and desire. What you've done is knocked us all the way to the bottom of the goddamn food chain. It's not a great leap forward in my book.
Answer: They viewed her as a villain because it was her research that backfired and caused all of the chaos, even though none of it was intentional and it was a mistake. But audiences can be ruthless and unforgiving at times. However, the ending did feel like a cheap cop-out that created more plot holes. And many do feel she should have survived and completed her character arc. I don't know why they never offered the ending as a bonus feature on the DVD, but fans started a petition on the Change site calling for Warner to release the original ending. Thomas Jane is on board as well, as he's promoting it on his Instagram account. So that's probably the best way to get Warner's attention if you want to see the original ending.
