Just read the book

Rating: 6/10 (21 December 2017)

First of all, I read the book and I saw the first IT movie.
This movie is not so bad, has a decent cinematography, even if some CGI scenes feels weird and questionable.
However, we see a vertical bokeh (artistic blur) on the background, which is really bad and deforms perspective, we usually see a round bokeh which makes soft bubbles of color, so it was a weird use of camera.
There is a clear overuse of wide lenses, which is a naive approach to horror atmosphere. Then even used it on a cliff (when they jump in the water), we the the cliff completely deformed by the wide angle and it's just an amateur mistake.
Characters do have different personas, but it's really cliché and instead of adding some backstories to them, the movie focuses on showing the Pennywise's trauma inflicted to each of them. This process is a huge issue in the movie because it takes way too much time, and it's systematic so very predictable.
Other big structure issue : this movie is focused on the past (from book's point of view), when they were children, so we lose all the confrontation between past and present, and this was actually an important aspect of the story. Maybe they tried to do it differently than the first movie, but I think it's more a commercial choice (like CGI use), so the first movie actually did better in this particular aspect.
IT is kind of scary, but it doesn' t add much to the story, there's a lot of random scenes where IT appears and disappears, it even disrupts the timeline.
I don't recommend, I just recommend you to read the book, and maybe watch the first movie. Might not look as good, but still a better adaptation.
