8. I Am Legend - Sam
There's nothing about a post-apocalyptic zombie drama that should be anywhere near feel-good, but there was literally no need for Will Smith's Robert Neville to see his trusty sidekick Sam cruelly robbed from him. Having been bitten by the weird zombie alien-looking creatures, Sam turns herself, but luckily Robert has the presence of mind to squeeze her head until she dies. Cuddles to the very end. This is the sort of outrageous, unnecessary death that usually has pro-animals rights campaigners so upset. Why does it always have to be the dogs? And why aren't they ever equipped enough to fight off zombies? They're clearly far more prepared than humans.
