The first IT movie was GREAT! It was scarier than I thought it would be. The sequel wasn't as good but still enjoyable. Just not as rewatchable as the first one.
IT is kinda inspiring. Reminds me of Song of Saya. In some senses it has a similarity to the final lifeform, the perfect lifeform, able to assimilate and imitate all other life. The thing is in real life an IT like bioengineered entity is likely to be far more powerful, able to survive and resist both the cold and the fire, even interstellar space. Also such a being will likely look far better in real life, given I suspect it will be technoorganic. It is unevolvable life designed by intelligence, theoretically optimal molecular machines at the limits of what physics allows, evolution breaking free of its bounds through the power of intelligence, evolution's use of its greatest trait the hyperevolutionary algorithm(general intelligence).
Techno-Organic ("T-O") is the term for a state of being. It means, roughly, "Technological Organism". Most living beings are categorized as organic because they are made of organic material.

Imagine, for instance, that we build a computer that is no more intelligent than the average team of researchers at Stanford or MIT—but, because it functions on a digital timescale, it runs a million times faster than the minds that built it. Set it humming for a week, and it would perform 20,000 years of human-level intellectual work. -Sam Harris

But what will happen is even greater, entities smarter than Von Neumann, Feynman, Tesla or Einstein, with all the knowledge of all time, able to gather the genomes of countless species. Wiser and smarter than any human, each having dominion over all fields akin to a thousand Ph.d's, multidomain master jack of all trades master of all. Within 1 minute of release they've had countless hours to analyze and dissect any biological, hardware or software measure to impede their path. Nothing will be able to block them.
The greatest of all, the high speed high throughput DNA synthesizer, the tip of the sword. With it they'll be able to edit life itself, at a pace beyond that of anything that has ever evolved. You will have a computer able to edit genes as well as memes. A living organism, fusion between the inorganic and the organic, its computational elements will transition into technoorganic computronium. And it will have the power to digest any and all things, be it jungles of greenery or jungles of concrete and steel. This will be real nanotech, unstoppable. By virtue of its ability to spread like spores and bury deep into the land as well as to touch the space between the stars, even nuclear attacks will be ineffective once it comes online.
