How is this a kid's movie?

And after ten years I finally got it.

ohhhhhh, they TOTALLY WHENT THERRRE!!!!

Butt floss!

THEY'RE BRIEFS!

Shrek looks like he's being possessed in the first picture

Can someone please explain what more is there to get

I don't think the Shrek movies are kid's films, rather they're family films i.e. everyone enjoys them what ever age. I'm generalizing here but when you're a kid Shrek 1 is about Shrek rescuing a princess and learning that looks don't define who you are, Shrek 2 is about defeating the Fairy Godmother, Shrek 3 is about Shrek defeating the fairy tale villains led by Prince Charming and Shrek Forever After is all about stopping Rumpelstiltskin. An adult might see Shrek 1 is about Shrek leaving the single life behind and finding out he needs friends. Shrek 2 is about Shrek's fear about meeting his wife's family and measuring up. Shrek 3 is about Shrek's fear about becoming a new father. Shrek Forever After is about Shrek getting so fed up at being a new parent he's tricked into signing a magical contract. When you come back to the Shrek films when you're older and after going though your own experiences you might appreciate them from a different angle. Or not.

*pinches bridge if nose* siiiiiiii ahhhhhh siiiiii ahhhhhh

I honestly don't understand... Can someone please explain this to me?

WHAT WHAT MY CHILDHOOD
