In 2019 We had the Sequal to 2017's IT. But unlike that film IT: Chapter 2 was not as well received. But why not, What was wrong?
Well find out here: https://www.youtube.com/watch?v=-9JGu6msEKI
Right, now that I've seen your nitpicky video, I'll bite:
The same actress plays Eddie's mother and wife, but they look different, but are described in the book as similar in personality. Hell, the crappy miniseries didn't even bother with a wife, but had adult Eddie still living with his mother!

Pennywise went after the gay guy because he was his first meal in 27 years after waking up from his forced hibernation, so he was absolutely famished for ANYTHING to eat. The first film said that Pennywise will go after adults as well, even if they're not as tasty as children, but the book said the same thing, too.

There wasn't too much exposition, that's how it was in the book, and how full of it was the second half of the crappy miniseries? A LOT. Nope, since they were adults, it was inevitable they would discuss the history of Derry in detail and the details of IT, and I didn't find it too much at all. Heck, they even raised the stakes in this adaptation, which made the urgency to remember everything and then kill Pennywise so much more satisfying. And to be honest, I don't like those movies that don't tell you much and leave you to guess things for yourself.

The flashbacks were necessary as the adult Losers had completely forgotten what happened to them as children, because of the PTSD caused by Pennywise. Besides, I think the flashback scenes filled in gaps from the first film, like other encounters the Losers would've had with Pennywise (it surely couldn't just be the ones in the first film) and we get to see iconic moments like the clubhouse.
Remembering the past was all-important, and the book did it anyway too, so why are people complaining? Also, it was nice to see the child actors again.

Unlike you, I had no problems with the meteorite scene at all, it was all explained perfectly, if only you'd listened. The Native Americans described, in a vision, as the book did, how IT arrived, and how it fed off of humans when they arrived in the vicinity millennia later, and how it basically lived for thousands of years. The book described IT arriving in a meteorite in very much the same way, during two of the Losers' vision quests. I only wish we could've seen the ancient flora and fauna from then, too.

The Muschietti IT movies, like the 1990 Miniseries, are ADAPTATIONS, so not everything gets transferred from book to screen in the same way, and to be honest, there were some things about the book that was bad: everyone agrees on Beverly having sex with each of the boys in turn to be a bad thing, and it seems both adaptations also agreed on Pennywise being a female and having the Losers contend with hundreds of eggs was also a BAD THING. So they didn't include them.
Don't forget, Stephen King was high on drugs when he wrote some of the book, so it's probably best not to indulge his weird psychotropic highs in writing.

Seriously, an arcade machine? You're really nitpicking here. WHO CARES? Most people would not even notice, and it wasn't even that obvious, not to me, anyway. And there were contemporary cars in the street in the first movie that others noticed that were out of place, I wonder why you didn't.

As for the derelict arcade decades later, the machines looked heavily damaged and even vandalised to destruction. You're the first person to mention the supposed value they might have, but if that were the case, the cinema itself would still be operating, let alone the arcade. There was probably some sinister reason why the place was abandoned.
As an aside, if old arcade machines are so valuable, then why wasn't Flynn's Arcade in Tron: Legacy raided and have the machines stolen, or sold off? They were treated with a lot more care, too, so they were working. Why not them?

As for Silver left outside the funfair, maybe you have a point as to why it wasn't taken by any of the crowd there, but then I figure they thought it was rusty and worthless and almost broken, so they just left it. Seriously, it's another nitpick.
As for Silver being left outside the house on Neibolt Street? Let's see, it's nighttime, and the house is creepy and probably haunted, and many bad things have happened there. Who would dare go near it at that time? Another nitpick.
