Am I Excited to See "The Runaways"?

I'm serious here. Am I actually anticipating the release of the new Kristen Stewart and Dakota Fanning starring movie The Runaways? A movie about two people I know nothing about (Joan Jett and Cherie Currie) dealing with a relationship I had no idea was tumultuous? The Runaways as directed by Floria Sigismondi, who I have never heard of and therefore have no pre-formed high or low expectations over? There isn't even a trailer swaying my excitement, but I can feel it. This is what being excited feels like. 

Now that I've come up with an answer for the first question (the answer was "yes") I have yet another question: why am I excited to see The Runaways? I have only seen Kristen Stewart act competently on two occasions, with an almost invisibly small role in Into the Wild and a not-great but not-painful supporting role in Adventureland. No way do I consider myself a fan of her work. Nor do I think I've been pleased to see Dakota Fanning lead a film. 

Maybe I have a secret admiration for female rock stars? A deep-seeded love for biographies of any variety? I don't know. It's confusing me more than the time I went gaga for the Cherrybomb trailer. The Runaways is apparently being released on the 19th of next March. We should have more of a peek at what's really going on with the movie by then after Sundance has strained it. Right now we have this to go off on, and apparently I've been wowed:
