Didn't expect this film to tie things so nicely.
It's a bit depressing that everything has to be so old and derelict, like the equipment, Ecto 1 car, heroes forgotten, why is it, when a new sequel of anything comes out, all the previous achievements have to be destroyed.
A lot of years did pass, but not so many, as to have a third generation - could have main character's children in their 30s as the new leads. There was no Egon's daughter mentioned in 1989 Ghostbusters 2, but there is one here, old enough to have 15 and 12 year old children. She must have given birth to the first one at 16 herself.
I do like McKenna Grace a lot, so that saves it a little, but the whole Stranger Things element was obviously at play here.
Also 'diversity' doesn't sleep here. I'm all for fair and realistic representation in film, but for a rural Oklahoma town to have not only more, than a couple of African-Americans (there's at least 4-5 characters here, including the sheriff), but also an Armenian guy, a Korean kid, an indigenous Canadian, and a transsexual Hispanic, who are all hanging out together, feels a bit forced. Hollywood propaganda in your face forced.
I would want more screen time of the original cast, even though they got old. There should have been more sequels with them, earlier. In the 90's, then a couple more in 00's. But as it is right now, I guess it's the best we could hope for. This is how you respectfully make a sequel so many years later, while honoring the original cast and characters.
Not whatever that 2016 abomination was.
