Boring, but fine for kids
I have to disagree with the overall age rating. It was just fine for our 5 3/4 yr old girl and 7.5 year old boy. The sexy humour went over their heads. They had just seen the cartoon 2019 Addams Family movie earlier in the day and wanted to see this original. But for them, and mom and dad, we were all a bit bored. Yes some of the fun 'Thing' scenes amused. But the story of a long lost Uncle Fester coming back an impostor trying to steal their fortune was old and tired. It's not for the acting. I think Angelica Huston, Raul Julia, Christina Ricci and especially Christopher Lloyd did terrific jobs recreating the characters from the TV show. But the story/the script was just flat out boring.
I seem to recall watching Addams Family Values some 25 years ago and I think it would be more enjoyable because, based on my memory it was a more Wednesday and Pugsley focused story - something my kids would have been more interested in. However, I think this one killed their interest in watching any more Addams Family movies.
Having read all the other reviews here, my wife and I were all set to have conversations explaining the challenging parts to them, but perhaps my kids are more exposed to things than others because nothing in this movie phased them. They understood it was over the top pretend. We never needed to explain anything. Yes there were a few swear words. Nothing they haven't heard a thousand times before. I tried really hard to understand what scenes were the overly sexual ones that other reviewers talked about. I saw none! Yes, Gomez and Morticia flirt constantly. So what? From my 5 and 7 year old's perspective that just means they like to kiss each other a lot - which to them is yucky! I really don't see what other parents thought was overly 'sexy' here..
As a result, I'd say this movie is fine for most any kid that isn't extremely sheltered. It wasn't scary to any of us.
The only bad thing I have to say about it is, well, boring and not a movie that any of us enjoyed. It wasn't worth our collective time. So, avoid if for that reason. Otherwise its fine.
