One cool one with her is The China Syndrome. Julia and Coming Home are good too, but not because of her haha. I've never thought she was a great actor; I love her dad, really. Pretty much anything Henry Fonda did was gold, whether he was in early noir or my favorite film Fail-Safe (1964), he had magic to him. I always want to like Jane Fonda, but really I don't like the acting of any of the kids; like Peter Fonda is damn near unwatchable to me.
It's this weird thing with the kids of great actors; they can often have so little feel compared to the parents. Like, Kirk Douglas and George C. Scott are great, but Michael Douglas doesn't even compare and Campbell Scott is made of wood.
Kirk Douglas once said that, unlike his kids, he had the advantage of growing up in abject poverty.
