First Trailer for CW's The Flash

This is the trailer that aired during Arrow's season two finale. I don't watch Arrow, but I am definitely intrigued by this show although I am not completely sold on the suit (too much forehead) I think the trailer was pretty good.

I like the special effect of the Flash running, and Grant Gustin portrays Barry's more upbeat personality well in the couple lines he has. I wonder how tied to Arrow its going to be though. Anyway what are your thoughts?
