Do you think Broadway messed up American Idiot?

I've listened to American Idiot many times so I know how the storyline goes. I've watched some clips of the American Idiot cast on GMA and I feel like they kind of messed it up. The main character has a British accent (and seems to act kind of gay) and I pictured Whatsername to be white. I'm not being racist or anything even though I do think they did a good job of making her look punk. What do you think about it? I haven't seen the show yet so maybe once I see it it will surprise me.
