Okay so I liked it better than Afterlife, which isn't really saying much because I really didn't like Afterlife.
It at least tries to be it's own story and have it's own identity beyond just screaming "HEY, REMEMBER GHOSTBUSTERS (1984)???? DO YOU??? REMEMBER PROTON PACKS??? AND ECTO-1?????". The original cast are worked into the plot in a more natural way that doesn't feel like cheap cameos (like before!) and there's some pretty interesting expansion of "Ghostbusters" as a concept which is nice to see.
Which isn't to say that it's good, though, because it's not really. It's painfully average. There's like 30 side characters and about two are interesting to watch. There's a billion sub-plots, including a good ol' gay romance that isn't excplict about it so they can still make money in countries that hate gay people. The callbacks that are there don't feel annoying this time, just... pathetic? Like are people cheering for the return of Walter Peck, or The Guy Who Ran The Library?
The Peck thing is interesting because he's just doing the same thing he did back in Ghostbusters - namely having extremely valid points that are dismissed because he's an asshole about it. In the original it was "Hey maybe having a bunch of random guys use unlicenced nuclear equipment in the middle of a well populated area ins't a very good idea", and here it's "Hey maybe bringing your underage daughter to fight ghosts in ways that could actually kill her isn't a very good idea". But we're supposed to think both of those things are unreasonable!
But the worst thing is that it's just not funny. Like, Ghostbusters, Ghostbusters II and YES EVEN Ghostbusters (2016) are at least obviously comedy films. They sort of forgot about it here, so it's just a generic action/adventure film with Marvel-grade comedy (which is to say: bad). There's maybe two laughs in the whole thing?
So I guess I just thought it was kind of 'eh' rather than actively bad like Afterlife was.
The mini-puffs still fucking suck FUCK YOU YOU FUCKING FUNKO POP MINION PEICES OF SHIT I HATE YOU.
