There's no debate. Jenny used forest and threw him away as soon as he didn't have what she wanted. When she ran out of places to go, she comes to forest just to torment him, get pregnant, then run away again. Then, she appears out of nowhere to hand off forest's kid that she had been hiding from him for years right before dying of the aids that she probably also gave to forest.
That snippet isn't what the movie is focused on. It's just the actions of a side character, who has a big effect on the main character's life sure, but it isn't what the movie is about. That's like saying LOTR is something you wouldn't enjoy based off nothing but a description of Gollum's role in the story and nothing else.
That was a pretty accurate, if cynical, read of Jenny's role in the story. But that's definitely not a good summation of the story as a whole. Forrest is the protagonist and his relationship with Jenny is more a recurring blip on the plot than the actual plot itself. Forrest's story is fantastic and and compelling independent of Jenny. It's still worth a watch, I promise. Can't speak on the book, but I've heard it's good too.
I was kinda being mean just for the sake of the meme. I know there's a lot of nuance when it comes to Jenny and forest's relationship. I fall into the "it's understandable, but still not justifiable" camp.
I totally agree about the movie. Easily one of my top 10 movies
