I recently watched a 3d video in a small theater about dinosaurs, and in the video we follow a T-Rex mother from her first eggs to death, including a fight with another dinosaur that ends up crippling a leg, and then the last few shots of her are limping toward carrion to survive a little longer, and then dead in a creek bed and I legitimately almost walked out of the little theater we were in.

I may have smoked a little before going in, so I may have been a little more emotional than usual. But still.
