YES ! Supergirl's pilot leaks online !
After only few days since the series first footage was unveiled last Wednesday, May 13, High-quality (up to 1080p HD) copies of the pilot for CBS drama “Supergirl” — which wasn't set to air until November — apparently leaked onto file-sharing and torrent sites early Friday (shortly before 3 a.m to be precise). Which makes it available for fans to watch almost 6 mounths earlier than they were expecting!
I just watched it, and it was super dope! Sure, it wasn't as cool and well done as The Flash's Pilot was, but it sure was much better than i expected after seeing the Trailer!
Here's the trailer by the way in case you missed it!
