I know the feels. Probably wasn't a good idea for me to buy that 30-film Universal Classic Monsters set when I've still got so many other unwatched Blu-rays!
DO IT. Chapter Two was everything I wanted and more. I wanted it to be weirder and more grandiose, as well as to have the timeline-jumping that the book does, and it delivered! It's rumoured that Stephen King is writing a new It book! I wish he'd hurry up and announce it.
No I completely agree with you. Chapter One was really good but Chapter II/2/Two just amplified everything. I love how it just took its time to tell the story and didn’t rush through anything. Ugh, now I want to rewatch.
