This movie is great but I have a major idea for chapter 3. Let's get into the scientific origin of it and maturin. Showing their massive battle casting out it into earth (sounds almost like a biblical story) but allowing to see why it attacks humans as if he's trying to absorb the soul power of humans to later fight and win against maturin. With the losers club 27 years later being elderly, have it come for their grand children seeking revenge for what happened 27 years ago. Since, their parents (original losers club members offspring) has no idea of what happened being kept away from Derry for some weird reason, the grand children of the losers club each come in contact with something that fears them and is coming for them one by one starting with the strongest the children for their wild imaginations. Have the remaining loser club members die one by one leaving just the original leader to inform the grand children of what to do. Have the grand children meet each other due to seeing the same monster, talk about it on a social app comparing stories and some object looking like a clown saying "one will kill one will die, jorge is here just come to the light". After meeting up have one of the kids say their grandparent revealed an old campfire story about some alien creature from out of space that looks like a clown lives in Derry. Have the kids dream about pennywise and the history of what went down, and how he's coming for all of them family included. Have the parents get kidnapped by pennywise threatening if the grandkids didn't show the parents would meet a horrible end. So the grandkids make their own group called the winners club, since the losers club didn't fully contain it. Have the kids go back to Derry to find their parents but run into it.
Have the producer feel in for the main part to make it seem great
But for the conclusion for everyone to understand about the book. Have the winners club stumble apon the ritual of chud, but have a special prism to chant with during the ritual but instead of containing the dead lights it summons Maturin in his main form. It acts scared trying to attack the kids but the turtle (Maturin) keeps on attacking it. Towards the end, Maturin opens his mouth to consume it. But as he swallows air like a forceful whirlwind sucking up everything having the kids hold on for dear life. Jorge appears to his brother and says you know what you have to do, now do it. Bill looks at his grand daughter (who is the leader of the winners club) tells her he loves her and for her to stay with her friends. Bill then let's go flying into pennywise knocking him loose into the mouth of Maturin( both of them get sucked up). Pennywise is finally destroyed and maturin talks to the kids about how good triumphs over evil and to get back their love ones and all who were taken by the evil. They go back home in search of one object that brings peace and love to the mind to burn and be placed under the moon during a full moon. A powerful blast of light and energy gets shot down from Maturin's mouth and after a flash of light all who were killed comes back to life bringing all who were hurt back happy.
