Lena Dunham is too young to appreciate/understand Star Wars. I'm not going to fault her for that. It's just not her thing.
According to Wikipedia, Lena Dunham is 28 years old this May.
When Episode 1 came out, she was 13.
Whatever you want to say about the prequel trilogy, kids who were 5-15 when EP1 came out, SAW it.
This is nothing more than an actress/"writer" who thinks her s**t doesn't stink, acting like she is "above" Star Wars - nothing more, nothing less.
