My character in 'Prison Break' needs to be formidable. In reality, I'm not very tough at all.
I don't think you need to watch Arrow and Flash to appreciate what it is Legends has to offer. The beauty of this show - and they do this on Flash, and they did this on Arrow - is that we do spend time on character. We do spend time on backstory. We do take a moment in between the sci-fi special effects to tell you who these people are, so that when something happens to them, you actually care.
I think it's necessary when you're dealing with a dark show that has explosion and violence to have defined moments of lightness and humor, even romance. It's important, and it deepens the character, of course.
I think ultimately that's why the audience will tune in longterm, for the characters and the relationships.
A ghostly side note Soldier boy Miller played a Lucifer-like character in the final two episodes of Joan of Arcadia. Coincidence I do find it strangely poetic, ... that a character who shows up on a show about God to play something kind of satanic winds up in the very last two episodes of that show, and then appears in the show that replaces that show on its exact time and night the following season.
I'd like to go back and revisit the Flash/Captain Cold relationship, because that to me has been the heart of it all along. My impression is that The Flash is a show about a boy's journey into manhood. For the Flash character, there is a variety of male models presented to him, and Captain Cold is one of them.
On Flash, I thought of myself as a spice character; come in, do a little dance, and I go.
