This movie, more than the other one promotes that being true to yourself will always be the right thing to do.
Violence wise it's not appropriate for young children and it's especially scary when the baby is the intended target.
Uncle Fester falls in love with a woman who is intent on hurting him and some sexual content is involved.
There's more bad language in this movie than the other.
Iffy for 13+
Well right off the bat there is a reference to sex and how babies are made so definitely do not allow children under 14 to watch! The violence was worse than I expected with showing siblings intending to behead their baby sibling! I do not recommend this movie in general.
