Most kids watched Robocop but that's a dumb comparison. The ones marketed to kids were kid friendly. I had loads of them.
Ghostbusters was on EVERYTHING from day 1. From pencils to food to toys to clothes, it was impossible to escape.
Robocop was marketed later to kids after it took off. Could be the fact if was classed as 18's so harder to see in the cinema/rent the video.
I had the Robocop voice changer and felt like the coolest kid on the planet buying things in shops.
I don't remember Ghostbusters being on everything from day 1. I remember them trying to milk it after it became a box office success. Then again, i'm from Europe so i don't know how it went in US.
There is a difference between a movie being made for kids and a movie that can also be watched by kids. Ghostbusters is a movie that can be watched by kids because there isn't anything too inappropriate for them in it, but that doesn't make it a movie made
for kids. Marketing also doesn't tell you anything since they can market anything to kids, even Robocop and Mortal Kombat.
It's the content of a movie or game that tells you what it is. All you need to figure out how Ghostbusters certainly wasn't made with kids in mind is to watch it as an adult. Same with other movies that might look like kids movies such as Who Framed Roger Rabbit. There is a ton of comedy and subtleties in these movies that only adults would appreciate.
The only thing adults can get from Afterlife is the references. And boy, some of those, especially near the end of the movie, felt so forced and awkward... Like the "who you are going to call" or "are you a god" lines. REMEMBER THAT?
Other than that, the actual story and characters seemed too childish to me. Children finding out Ghostbusters equipment and busting ghosts day one seems like a children movie concept to me. And there was almost no comedy at all, which is the biggest red flag since the original was a very funny movie. And the kids were unlikable. Oh look, it's Podcast, the quirky kid who knows internet stuff and has subscribers, am i right fellow kids? He even carries his streaming gear with him, come on. Oh look, it's the snobbish black girl who is too cool, too perfect and too smart to be impressed... Does our awkward, skinny boy have any chances with this goddess? And sure, Paul Rudd is a funny guy in other movies but here he is just... the likeable fella.
I just couldn't be invested in this at all.
