Somewhere between a 3 and a 4 star.
There was just a few things
*Length. I feel like a mixture of I didn't enough of what I wanted but it could also lose 200 pages somewhere.
*That controversial scene feels super unneeded for the "reason" like...now that IT is defeated where is our bond? IT is the only thing we have in common and therefore we have nothing binding us as friends anymore and Bev's like "even though we are 12 we can have sex with each other so we have each other's virginities and I can get my sexuality back from my dad". Is the knowlwdge and togetherness of defeating a monster not enough? Not to mention IT actually came back 27 years later and they all are reunited. Well, 6 of the 7 are.
*the last point is Further instrumented by the ending where even after defeating IT for the final time they forget each other anyway. Like forever. Forgetting each other and every part of each"s existence as both children and adults.
So then being bonded together that way is a " don't frown because it's over, smile because it happened" thing THAT THEY CANNOT EVEN REMEMBER ANYMORE. EVER!!
