A bit of a nothing burger, it doesn’t really get interesting until the final 20-30 minutes.
There are a few entertaining bits inbetween (e.g. there’s a fun scene with Paul Rudd in a Wallmart), but there’s not nearly enough going on.
It’s just mostly bland: some decent acting and directing, but there’s not a lot of action, mystery, charm, clever comedy, drama or characters to get invested into (besides McKenna Grace).
For example, Finn Wolfhard gets as much development as the older brother from Jurassic World, he’s a teen and he wants to get laid. That’s all you get, and it’s not that interesting.
There are, of course, a lot of ‘member berries, which add nothing besides empty nostalgia.
The original Ghostbusters leave the biggest impression with just 5 minutes of screentime, and they clearly didn’t even give a shit about being there.
It’s not the worst thing ever, but this falls short of the benchmark for this kind of movie.
Just watch the original, or anything directed by Spielberg and Cameron in the 80s/90s.
