Not half the movie Chapter 1 (or the 1990 version) was.

Rating: 5/10 (6 September 2019)

It: Chapter 2 is a dragging borefest with forced cheesy comedy lines which only server to tug the plot along. The CGI is worse than the CGI in the first movie for some bizarre reason (but it's still passable).
At least it's true to the novel (for example, the ritual of chüd appears), and Stephen King makes a cameo appearance. And to be fair, most of the casting is well done, Beverly, Eddie, Bill, Richie and Henry Bowers really look like they are the same kids, just aged 27 years.
If you liked Chapter 1 (which in my opinion was a fantastic movie) I recommend you do go see Chapter 2 just to see the story get wrapped up.
Beware though, Chapter 2 is not half the movie Chapter 1 was.
