The new CBS Supergirl series set to debut this fall has its first trailer... and WHAT THE EFF. It's GREAT! At first I was like, "a six minute trailer?" Then I was like, "I never want this to end!" Melissa Benoist as Kara Zor-El/Supergirl is freaking adorable, Mehcad Brooks as James Olsen is hot, and Calista Flockhart as boss lady Cat Grant is hilarious. I'm already overselling it too much... so just watch and oversell it to yourself.
