After getting a couple of live action versions of "The Addams Family'' in the 90's (which I loved), we get an animated version. Gomez (voiced by Oscar Isaac) is still crazy in love with Morticia (voiced by Charlize Theron). Wednesday (voiced by Chloe Grace Moretz) is still a monotone harbinger of doom and Pugsley (voiced by Finn Wolfhard) is still the frequent object of Wednesday's experiments to get rid of him.
This movie could be considered The Addams Family origin story. It begins when Gomez and Morticia are just getting married and also being ran out of town by an angry mob. They find Lurch (voiced by Conrad Vernon) and also find an old asylum at the top of a spooky hill to be their new digs. For them it was perfect. Life was spooktacular for them for thirteen years until a "Flip or Flop" type TV show led by a woman named Margaux Needler (voiced by Allison Janney) decided to renovate the town below the Addamses. This new town of Assimilation was everything antithetical to the Addams: it was clean, colorful, cheery, and full of Stepford people. A town such as this would not have a good value while being under the shadow of the Addams Family's dark derelict lair.
While Margaux plotted to make the Addams conform, Wednesday was going through a rebellious stage and even put a barrett in her hair, and Pugsley was having a difficult time learning the Marsuka (an Addams Family sword dance that was a right of passage). The Addams were facing a crisis of sorts. "The Addams Family" was mildly amusing and fairly entertaining. I don't think there needed to be an animated version, but that's Hollywood now: animate what was once live action and make live action what was once animated.
