Questions about Ghostbusters Afterlife

(Spoilers).  I had questions about this Ghostbusters film.  Probably everyone else had the same thoughts:
*I could have sworn I heard Bill Murray say "We're closed" in the previews, but they never used the scene.
*You could do a drinking game with the phrase "Dirt farmer."
*It would have been nice to see a different villain besides Zool.
*What, no Slimer?
*If you're going to ignore the PKE meter, why even have it in the plot?
*I wish this film featured Luis Tulley.  Why wasn't he in it?  I always liked Jeanine.  It would have been an interesting plotline.
*Funny to list Sigorney Weaver in the credits when she only appears for a minute.  But I *did like the bit with the cards.  I suppose Venkman deserved it.
*How do Phoebe and Podcast know how to use all the switches on the Proton pack and not blow themselves up?
*For a dirt farm, there sure is a lot of crop to joyride through.
*If the firehouse got turned into a Starbucks, why does it look abandoned and dusty at the end of the film?  Was that just a story?  Also, if it were* bought out, why didn't a barista go downstairs at some point, push a button, thinking it's a trash compactor or a coffee machine, and let all the ghosts out?
*They didn't really explain why Ivo Shandor looked so healthy in that glass case.  I guess you might argue something about Lenin.
*Why didn't Egon's ghost show them the fault in the giant capacitors?
*Being a gatekeeper has its perks.  You get to keep the magical wardrobe.
*If Ivo Shandor's name is on everything in town, why isn't the school more centered around him, showing more of his history or something?  Like Ivo Shandor day?
*Phoebe can pick the lock, and is a genius, but cannot pick a police contraband locker.
*I really didn't get a sense of time.  Was this summer?  Where was the principal?
*Interesting "summer school?"  You get to watch Cujo and Chuckie?  Really?  I'm wondering why the kids looked so bored.  Did they watch those movies last year?
*This is the first major motion picture where my car gets important screen time.  Now I'm thinking about driving my Corolla with no windshield and how unpleasant that would be.
*Finn Wolfhard doesn't have much charisma.  I expected more from a character that's supposed to replace one of the originals.
*Phoebe really steals the picture.  I couldn't tell who she was related to.  Kinda wished there was a Bill Murray type of child.  Not enough sarcasm.
*Didn't get a sense of any of the characters, really.
*I always pictured Egon being an Atheist.  What's with all that bible stuff outside the ranch?  Guess it kept you guessing about his identity, but it's out of character, and we already know nobody else is that clever with scientific stuff.
*What was Phoebe doing with that wall outlet?  Was she stealing electricity?
*At the burger joint, which is the boyfriend that owned the jacket?  We never find out.
*You have a Proton Pack.  Why do you never bring along the PKE meter?  You would have avoided a lot of close calls.
*Did Podcast know how to use the trapdoor in the Ecto 2?  Or the remote control?  
*I think the Proton Pack should have thrown Phoebe across the field.  Also, she has considerable muscular strength to carry that thing around.
*She was lucky not to have the building collapse on her head when going after The Muncher.
*Phoebe's banter with Mr. Grooberson was great.
*Turning an entire property into a ghost trap?  What's to stop it from sucking the soul from your body, or trapping Egon's soul?
*What happened to all the cops in the police station?
*I appreciated the mold collection and the Twinkie.
*Baskin Robbins product placement - boo.
*Effective job bringing Harold to life.  Good move to make him not talk like they did in Rogue One.  Let the dead rest, man.
*I knew someone was going to call the number for the Ghostbusters sometime, she has no other special phone number, and yet they felt the need to repeat the fake commercial, I guess for people who never watched Ghostbusters 1?
*Surprisingly low key reaction to seeing the Ecto 2, considering their recent studies on the subject.
*In life, Egon did everything he could to stop the apocalypse.  After death, he tells his granddaughter how to find an ecto trap, without warning her that opening it would doom humanity.  Mind you, I'm talking about supernatural warnings, and not talking.  You know, like throwing her across the parking lot, shorting out the trap's release mechanism.  That kind of thing.
*Someone should have come after Mr. Grooberson about the buses.  Of course, it explains the horror videos.
*Also, if Pheobe's classmates are "stupid" and he plays those movies for them, what does that say about horror fans?  Or maybe the fact that it bores them is a sign of their stupidity?  I don't know.
*The "Giant dog" actually eating dog food?  It ate people in the first film.
*Why does the demon dog need to possess a person to become itself again?
*Zool's costume seems better this time around.  The first film...It looked like a guy who had just stepped out of a bubble bath.
*Why does Mr. Stay Puft act so suicidal?  They seem to enjoy being toasted.
*Where did the other Ghostbusters get all the proton packs if Egon took all of them to his dirt farm?  Surely they can't build the things themselves...right?
*I wish they made more use of the Death Whistle.
*The gatekeeper and keymaster didn't have memorable dialog between each other, but I think a lot of parents will be using "There is no mom, only Zool" from now on.
*Winston has aged the best of all the Ghostbusters.  They basically proved that their chemistry cannot be replaced.  Great lines.
*Clever, jumping through the smashed windshield.  But not the best plan if you don't immediately pop out the door, or hit the gas pedal.
