Pennywise targets children instead of adults because they are easier to scare and manipulate. Their fears are often simpler, more direct, and easier for Pennywise to exploit.
This creature feeds off fear and its preferred victims are children as their fears are simpler, but there might be another very different reason for that, and it's rooted on the real meaning of IT.
It has a preference for children since their fears are easier to interpret and adults are more difficult to frighten while It is in physical form. It can manipulate weak-willed people, making them indifferent to the horrific events that unfold, or even serve as accomplices.
This twisted extra-dimensional entity had a form a human could only comprehend as a giant spider, but It would almost always disguise Itself as a clown named "Pennywise the Dancing Clown" to attract children so that It could capture and kill them as they were an easier target.
Georgie Elmer Denbrough is a fictional character created by Stephen King from his 1986 epic horror novel It. Georgie is the younger brother of Bill Denbrough, and falls prey to Pennywise the Clown. He is used by Pennywise to taunt Bill throughout the novel.
They reach the conclusion that Pennywise has all of the adults under some sort of spell that prohibits them from seeing him. The adults of Derry are shown to be villainous in their own right as well. The adults of Derry are shown to be true villains of the story in the same way as Pennywise.
A common interpretation of this phrase is that it refers to where the souls of IT's victims go after they die, as they wouldn't go to heaven nor hell, staying instead in the “deadlights”, which would be a sort of limbo, thus “floating” in that middle point for eternity.
Stephen King's IT introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
Pennywise may act like a silly, childish clown, but he is still a murderous, killing creature. He kills for a living because villainy is in his blood. He enjoys wreaking havoc in the city of Hometown, and he is smart enough to know about a child's fear.
Finally, Pennywise tears off Georgie's arm to make sure Georgie knew he was going to die. Does Pennywise (IT) have to eat and kill only children? No, that's a common misconception, IT only prefers to hunt children because they taste better and IT has more fun with their fears.
Throughout the book, It is generally referred to as male, usually appearing as Pennywise. The Losers come to believe It may be female after seeing it in the form of a monstrous giant spider that lays eggs.
Yup! He's a demon and the general idea is if you are not scare, it will only be harder for Pennywise to kill you as he needs to bait you. He can kill you if he wants to anytime and doesn't care. Although, if you are not scared, he will either leave you be for a little while or just kill you in the instant .
IT arrived on Earth through an event similar to an asteroid impact, landing in what would later become Derry, Maine. Once there, IT adopted its usual pattern of hibernation that lasted between 27 and 30 years, awakening to kill and eat and then going back to sleep.
According to It, when humans got scared, "all the chemicals of fear flooded the body and salted the meat". This is why he prefers to feast on children -- their fears are simple, pure, and powerful compared to the complex, pathological fears of adults. Basically, children are delicious.
Unfortunately, King's imagination ran a little wilder than alluded to in the movies or earlier in the books, and the consequence of that is a pregnant Pennywise.
IT is a shape-shifting creature known as a Glamour who is billions of years old. Although it lived on planet Earth for many years, Pennywise originated in a void/dimension outside the regions of space known as the Macroverse.
In the novel, It's origins are nebulous. He took the form of a clown most frequently, Mr. Bob Gray or Pennywise, but his true form is an ancient eldritch entity from another universe who landed in the town that would become Derry by way of an asteroid and first awoke in 1715.
It describes that it prefers to kill and devour children, not by nature, rather because children's fears are easier to interpret in a physical form and thus children are easier to fill with terror, which It says is akin to marinating the meat.
Pennywise had targeted Georgie when the boy was too young to know any better or fight back. In the clown's most contemptible murders, Pennywise did not rely on visions or fears to lure Georgie in; instead, Pennywise exploited Georgie's trust and turned it into a fatal weakness.
It runs away to tend to its injuries, but Bill, Richie, and Ben chase after and find that It has laid eggs. Ben stays behind to destroy the eggs, while Bill and Richie head toward their final confrontation with It. Bill fights his way inside It's body, locates It's heart, and destroys it.
Throughout Stephen King's It, Pennywise is referred to as a male, but author Stephen King pulled a fast one on readers in the It book ending by revealing the creature's true form was a pregnant spider, implying that it is, in fact, biologically female.
I recommend this film to everyone who loves slightly disturbing films and TV shows like me but for anyone under the age of 13 you really should not watch it. It's very gory and contains adult language.
