finished It.
I thought it did a few things better than the film adaption. The brain fog where they kept remembering details was good, because it hammered home that experience you'd have of someone you haven't seen since a little kid, or memories hidden deep within.
Beverly also seemed more slutty as an adult in a confused way where she was just ready to fall in love with anyone.
Also the final spider gremlin form.. I can see why people hated the spider in IT Chapter 2 now. That was just Pennywise, whereas this sold you on it being an outer space entity.
