I hope it gets a sequel. There is a lot that could be done with the material and mythos.
I think that Sony has mentioned wanted a sequel and a spin-off movie with a male team. Those two movies would deal with the teams confronting Zuul and Vinz Clortho, then the teams would join forces to fight Gozer in an Avengers type film. They also seem to want a Slimer animated film.
Yeah, this is what Sony wants, hence the "Ghost Corps" production company logo at the beginning, they want an MCU style property which, really, is kind of thinking a bit broad and big for this property. I'd be fine with just a series of films with this crew but I don't really see a need/use for a Slimer-centric kiddie movie or other teams of Ghostbuters leading to a multi-team teamup to defeat some big-bad from... another apocalyptic event?
If I had one nitpick, I wish Kevin was more of a normal character and not a dimwitted one because... reasons.

Chris Hemsworth is a good actor for the role but he could have been given more to do (IMO).
I think making him dim is fine, but they could have done it without making him rock stupid, removing the lenses in his glasses because the lenses bothered him... Which... I'd think not being able to see well would bother him more; and then him closing/covering his eyes to stop hearing is just over-the-top. Want to make him dumb and clueless? Fine. But making him this rock-stupid is too much. The stuff with his dog's name was fairly humorous though.
I wasn't entirely clear on Kate McKinnon's character background. Was she a physicist too? She was apparently an expert at building and engineering devices, but how did she or the team come up with the resources to fund their operations?
Kate, for me, was a great part of this movie. Her character's background seems like it'd be more centered in engineering but since she had some knowledge of nuclear technology she's likely a physicist on some level. But I did really like the scene where she had her "stand out" slow-mo battle moment with the proton-pistols with the new instrumental take on the theme. The action scene really worked for me, I also really liked the proton blunderbuss Kristen used during the battle.
The humor for me is a bigger problem and I hope in any sequels/spinoffs they don't got so low, obvious and cliched and the ad-libbing stuff really can be toned down; that led to a lot of scenes with humor in them where they kept hitting the joke over and over. The stuff with the name of Kevin's dog was ad-libbed but it worked because at least the joke was progressing in it's illogic. But then there's the scene with the "cat's out of the bag" in the mayor's office, the Patrick Swayze movie bit, the college dean and giving the finger. Stuff like that went on too long, past the point of the joke being funny anymore.
And going for the obvious:
There's the scene where they're putting together the plot of the "villain" with the metaphysical/spectral lines or whatever. Kristen Wigg draws several "X"s on a map of New York to indicate the various encounters they've had and then connects them with a larger "X" and asks if what they look like to everyone.
Kevin is standing there and studying them and he says "It's an X, crossing several other X's" or something to that effect. Which is.... supposed to be funny? He's DUMB we get it! You know what WOULD have been funny? If he said they looked like the metaphysical lines the villain was accessing. Him having this moment of lucidity and intelligence. something to cause a take and reaction from the crew. I'd think that'd have gotten a bigger laugh. Jokes need a PAY OFF and there's no pay off to the "Kevin is dumb" joke. He just keeps acting dumb and dumber and even dumber.
Something else: In the earliest trailer I criticized the scene where Abby while possessed turns her head almost all the way around, something that'd be devastating and deadly for a human being's body. But, fine, "she's possessed" and over the course of the scene we see Ronin doing things with Abby's body that'd not likely be something a heavier-set middle-aged woman would be capable of. Namely some of the jumps and physical feats like easily lifting up Holtzman to throw her out the window. But, fine, she's possessed and the ghost of Ronin isn't bound by physical laws and can do whatever he wants as a ghost through a human vessel.
But then when he inhabits Kevin he remarks about how much better that body is and marvels at his strength as he goes back to his contraption commenting he should have worked out more while alive. DUDE! You were in the body of a pudgy 40-something woman just 20 minutes ago! You were tossing people around, performing massive jumps, turning your head around almost 180-degrees, floating in the air and kicking the ass of two women in arguably better shape than your vessel. Clearly the strength of the body you're in doesn't matter!
