State of Origin Rep
You're right about the ending and they did take the cheap way out but overall as a sequel I thought it was quite good. I didn't go in expecting much tbh but IT surprised on the upside.IT 2. Could have been so much better, but the payoff for every genuinely creepy moment was a crappy CGI chase - over and over again. Lazy. It had it's moments, some of the performances were good but overall it looks like the film makers took the easy, cheap option.
There is a little bit more going on symbolically in the film for anyone that's into that sort of thing. The three dead lights for example, the concept of three lights as a symbol of death goes back a ways in art and what not. And a few back and forths between IT and Twin Peaks are of interest too.
Worth a watch, don't expect too much.
It was a bit long though.
On a side note I've never watched Twin Peaks so I didn't pick up that reference but Stephen King did like reference his other books from time to time.
In the Tommy Knockers he referenced IT which is one example that springs to mind.
