So for me, I'm like a huge sucker for big-blockbuster types, so I never really fell in love until Serenity (The Movie). I absolutely loved Firefly, but I didn't adore the characters until the movie. Even when I go through a run-through I get to the end of Firefly and I just think "Well that was pretty great, but not amazing." Then I watch Serenity and I'm like "Omg, that whole series was amazing!"
