Not in the slightest! Differences of opinion are what make discussion about film, books, ect . . . fun!
You are definitely right about the process of adaptation; book to film is a genre in and of itself. From my personal point of view, I just didn't think the film met my expectations for a good adaptation. Although, I will say the film was beautifully shot, and the cast was excellent!
I was extremely impressed with IT Chapters 1 and 2. The casting was fabulous, the dialogue was filthy and just perfect and I loved Pennywise.2. Sure I missed Tim's smart-ass quips and raised eyebrows, but Bill Skarsgard did a sweet job. I liked his choppers, too! Again, it was a treat to see Mr. King as Secondhand Rose's proprietor. Ritchie's coming out actually made sense to me, so kudos to that twist of events.
