Meanwhile, fans are looking forward to hearing more about Kara, as evidenced by the positive chatter going on all over the web regaurding the cast addition. This is in sharp contrast to the news that two new women have joined the cast over at Supernatural, which has fans in an uproar. This may be due to the fact that Supergirl is an already-existing part of the Superman story as told in DC comics, whereas the Supernatural newbies are unknown for now.
