My wife spotted it on Amazon Prime and we started watching it on a whim. It's an odd mix of comedy, action, drama, and romance all rolled into one. It's quite corny sometimes, but I really got attached to the main characters.
I hate the withdrawal depression that comes after finishing a long TV series or book. We watched 3 or 4 episodes every week for the past 7 or 8 months and now it's over. It's like a good friend moved or a family pet died.
