I loved this movie! Sure,it's not like the originals, but it's very funny (in its original gothic way). The voice casting was great, the animation amazed me, and it was fun to get in touch with my goth/emo side again. I really loved Oscar Isaac, Finn Wolfhard, and Chloe Graze Moretz in it.
Definently recommend showing it to the little ones, just in case they've never heard of the Addams.
