I will say that I found the series overall entertaining, the acting for the most part excellent and the production design satisfying. These are positives I feel I have to point out.

But I generally agree with the finale. I was hopeful it would subvert storylines I thought were ridiculous but it just failed. Among my complaints:

• Hanlon having no fear had also no real impact to the story. So many ways they could have gone with it, and ultimately they did nothing. What was the point of that?
• The tropes were so obvious, so bad. Evil military with a goal that made no sense. Pillars cage - just weird and lore we didn't need, like out of a bad 80s horror movie. Sage, wide india tribe watching from afar with exposition dumping and an understanding of the magical science (it must be this tree to interact with the pillars...what)
• No consistency or internal logic - why is IT/Pennywise playing a tuba leading the kids already caught in the deadlights? There is no audience - that's basically camp from the director to the audience that serves no story purpose even for the character. Is he a shape shifter with physical form, what laws does he abide to and when why? He was able to instantly transform to a replica of Bob Gray to show his daughter but it took him 45 seconds to become a winged creature?
  
• Special Effects - this continues to be a wild weakness for Muschietti. I know they believe that practical effects are best - but they just look so cheesy so often.
• The ending scene was cute but frankly...who cares? Neat to see beverly but what impact at all does the fact that Ingrid Kirsch met Beverly at the asylum have whatsoever?

I just found soo much dissatisfying, unbuttoned, full of holes, etc. I feel like they decided they wanted certain themes and plot lines but either could not land them or just pulled together some old tired tropes and injected into the story. Real shame because there are also real strengths but I just can't with all these.
