The trailer massively undersold this show. It's not a crappy rom com. It's a female led story with some great prospects. I'm excited for it to begin.
....Well... This is awful... Really, really bad.... I saw only the pilot, so fingers crossed they remove all the cliché bullshit, not to mention the completely derogatory sexism masquerading as 'girl power' and these characters are less than two dimensional. And please, stop referencing superman as 'him' or 'he'... From the sounds of 'him', 'he's' an asshole
well, this is awkward... a show like this being renewed while GREAT shows are canceled. #FuckLogic .
