I don't know much about Grant Gustin, but he did a nice job on Arrow as Barry Allen. When I was a kid I was a big fan of the original Flash TV show so I'm waiting with anticipation to see this new one. I even hear some Flash cast members will make an appearance on Arrow in April, cool!
Anyway, I do wish the costume was a slight bit closer to the comic version, but in any case I'm just happy it's not a typical "CW hoodie and jeans" look. What do you guys think?
