Trying to word this with as few spoilers as possible.
I watched Avatar 2 last night and halfway thru there is a scene where the scientists go into a "whales" mouth and cut into its "third eye"/ pineael gland and extract the most expensive chemical in the universe, the ability to stop human aging.
This is after the "whale" is hunted, tortured and killed.
It's just so fucking in your face.
I like how they forgot about the entire point of the first movie, the creatively name unobtainium.
