Everyone that had seen at least one dystopian future movie before I Am Legend came out knew from the trailer—hell, from the movie poster—that, at the very least, the pet German Shepherd and sole companion of Will Smiths' Dr. Robert Neville, would suffer a harrowing experience at some point during the film. Probably, the dog would perish.

But film knowledge be damned, we were on the edge of our seats as Neville and Sam fought off zombie goons and their demonic dogs, and though it went as expected, it didn’t diminish Neville’s grief by any means. There’s a reason the Fresh Prince is Hollywood’s most bankable star: We cared more when he put Sam down after she showed the first signs of infection than any mercy killing in The Walking Dead.
