Had issues.

Rating: 6/10 (15 September 2019)

Didn't see the first but did an adequate job of standing on its own.
Found it very uneven throughout, though.
Obtaining the "relics" was hit and miss in coherence as Chastain's and McAvoy's were obtained in the present day. Hader's was cursory but his fight was in the present day. The other two already had theirs and the fight was in flashbacks that had nothing to do with obtaining anything.
Seemed to veer away from the rules they set up in favor of more visuals and the fight at the end had elements that looked pulled out of the filmmakers' asses when they were stuck.
They knew that denying the threats were real would destroy the threats, but decided to repeatedly ignore them.
Making fun of King's history of poor endings in his books was funny. The reference to John Carpenter's The Thing was good. And I assume the pomeranian behind the door was an ode to The Holy Grail's rabbit scene.
The town was very sedate vs. the bloodshed going on. A town that small would be in panic mode and would be flooded with news outlets.
For its length, they could have worked a bit more on the cursory character arcs for all six. I know it's time consuming, but it sure was long to begin with. Could have swapped that with other things.
What happened to the ghoul driving the Trans Am? If Henry took a knife to the heart and lived, why didn't he survive an axe to the head? Pennywise was an alien with supernatural powers? He fed on fear? But the little girl under the bleachers was not in fear. Pennywise was vulnerable to intense bullying?
It was entertaining and, although long, didn't really drag.
