The Addams Family is one of the coolest families, fictional or otherwise. Everybody from the show had some weird thing going on, which made it fun to watch.
I would say that while the whole family was creepy, it was in one of the most fun ways that creepy can go. It kind of had a Nightmare Before Christmas feel to it. Honestly, the creators of the Addams Family as an entity must have been pretty messed up - in the best way possible, of course.
Here's some fan art that you can find in its entirety on the Addams Family Deviantart page. But these are a few of the best!
