I finally got around to watching Ghostbusters: Afterlife a few days ago, I really enjoyed it. I really dug Carrie Coon's performance as the mom. She was great in Gone Girl and she showed she can carry a movie as the lead here. Strangely enough, Gone Girl was the only other thing I saw her in before this movie, but yeah, her career should definitely take off after this. I also liked the quirky banter with Paul Rudd, who is also great, as usual. You can tell chunks of the plot was forced around them hooking up despite her clearly being out of his league and even being weirded out by him initially, but by the end of the movie, it all ties together perfectly, and it subtly implies they might still have a "thing".
As for the kids, they're very well-fleshed out and given plenty to do with their share of funny jokes to boot, but I'll agree that their whole Ghostbusting was contrived and happened purely by chance or because the plot needed it to. There's also not a whole lot of Ghostbusting in the movie, which I guess makes sense seeing how the original Ghostbusters have long since moved on, but I would've liked to see more of what we came to see in the first place. It also doesn't do new fans who've never seen the original a whole lot of favors because it randomly throws in references to 1984 and just expects you to know them without really filling in the blanks. There's some small issues with pacing in the third act as well, but it was alleviated with a VERY satisfying ending that'll no doubt tick longtime fans' nostalgia.
4/5. Not quite up to par with the first one, but far better than GBII. Oh, and I still haven't watched that 2016 one yet, but I do know it starts with a queef joke from watching some reviews on YouTube... because of course it does.
