I didn't pay attention to the show to the level that I am now when I first heard it was going to air. Of course, I saw the commercials and I was just excited to see that Supergirl was going to be on network television. I had watched most of Smallville and while it was okay, for what it was, I was really hoping for more of an actual superhero action show, like we ended up getting.
So, I really had no preconceived ideas on who should play Supergirl and Melissa was an unknown to me at the time. It wasn't until about half-way through the season that I even realized that she was the same actress who played Marley on Glee. (I watched up until Season 5 and then dropped it). And to be honest, I really didn't remember much about Marley's stint on the show

In spite of my lack of knowledge about her beforehand, I now really can't see anyone else in the role but, her.
