Girls sucks to me like I'd say Star Wars sucks (in theory) to her. I've met a lot of women who never saw Star Wars at all do I'm not shocked really. Her show gets lots of praise so I assume it's just not my cup of tea is all. Plus call me a pig on this but she's naked in it often and that's something I'm not into witnessing.
I have seen a few episodes of Girls, and like you didn't really care for it. I don't think I'm the target audience though. Anyway, I am curious to see Lena's performance in Episode 7. It should be interesting to say the least.
Wait, she was the one who got cast, right? 
Wait.... so Lena Dunham WASN'T CAST as Leia's Brooklyn dwellling hipster/slacker/ne're-do-well daughter?
It's about RELAVENCE. And CONTEXT. If JJ Abrams or Larry Kasdan were making comments like those in her tweet, I might care. But since Lena Dunham has NOTHING to do with the production of Episode VII, I take her comments for what they are: MEANINGLESS.
People spend an awful lot of time getting bent out of shape over things that mean absolutely ******* nothing.
