I find that movies with Will Smith in it, are definitely worth watching. This film was great, but along the lines of Resident Evil, very similar. I'm an animal lover, so of course I cried when his dog, Samantha, died. I was overcome and overwhelmed with heartbreak, hope, and excitement. Unfortunately, I hate that he died at the end, but it was almost predictable. I would go see it, just be prepared, and bring a tissue.
