WHY DOES IT HATE? WHY IS IT SOOOOOOO MEAN?

Well, not necessarily, at least not in the novel.

Ben in the book sees the mummy. He was scared of the mummy from the movies.
Bill sees the photo of George, and that WAS scary to him because he thought deep down George's death was his fault.
Beverly? Got me. She heard the voices and then saw the blood. Not sure what that was about.
Eddie saw the leper.
Mike saw the giant bird, not knowing/remembering that he had been attacked in his crib by a crow.
Stan saw dead boy scouts.
Richie saw the teenage wolfman.

I agree that what it appears as doesn't always equal what a person would say they are most afraid of (otherwise, they'd see It as Henry Bowers all the time). But I do think It appears to them in some very primal, scary way that they may not understand themselves; like Mike and the bird, and maybe Bev and the blood in the sink.

Whores will have their trinkets.

As near as I can tell, "you bet your fur" is a reference to actual fur, like a fur coat - something expensive, that you wouldn't want to bet on if you weren't sure. So I dunno, I still don't get why they changed it.

The further a society drifts from the truth, the more it will hate those that speak it.

I forgive IT because it had scenes like this https://www.youtube.com/watch?v=bOUMIXbTM5U

I also felt jipped during the big finale, not just because of Eddie's poor death, but because Bill, Ben and Richie got reduced to nothing upon seeing IT's deadlights. So, Bill says his famous line without stuttering (which may have had more of an impact if it'd been set up in the first half, but it wasn't. It was just typed out in the 2nd part and spoken that it's something he used to say as a kid. Cool, but losing it's punch.)

I totally get that they didn't have the time or money to go into the whole, IT is pregnant, IT laid Eggs, Ben is sent to crush them and such. And there wasn't any chance of the Turtle. But would it have killed them to maybe go into the psychic battle of Chüd for one brief scene? Maybe having the three of them standing there, and one last scene with Pennywise appearing to taunt them (seeing his floating transparent head in the sewer didn't do it for me.)

Instead, they all just stand there hypnotized and doing nothing, not until Bev finds the stone and shoots it. The scene of them ripping IT's heart out was cool, but would definitely have been cooler to actually SEE it happen, not just their shadows. That was the moment when I was like "this reeks of SAFE, MADE FOR TV." It'd be one thing to show IT's child victims, but to not even show a fake monster heart... Whatever lol

I still like the first half of the film for nostalgia purposes, and I love the music, but yeah, the 2nd half and especially the ending left us all hanging.
