Here are my thoughts on Supergirl.
Back to Supergirl. After Superman calms Kara down, minutes after she has manifested her new found powers she realizes that Superman is playing the role of a hero protecting the denizens of Earth. She leaves only to come into contact with Tycho again, who takes her up to his satellite. Through an adventure, he eventually gets a blood sample of Kara. She comes out winning, however, because she gets the mysterious Sunstone, which carries a message from beyond. Next, Supergirl uses a stargate to conveniently go to her city of Argo where she uses the Sunstone to get a partial message from her father. Then she meets a Reign, a Worldkiller, who artificially born aliens that are basically killing machines.
