The Flash was always going to rise or fall on the shoulders of its 24-year old star. Fortunately, Grant Gustin's youth serves him well, and he is utterly believable as Barry tackles the twist of waking up from a coma with superspeed. He shines most via interactions with the older actors in Jesse L. Martin, Tom Cavanagh, and John Wesley Shipp. All three men handle their roles in the triumvirate of father figures masterfully as each pulls a separate side out of Barry as he becomes a hero. For her part, Candice Patton generates a different sort of chemistry with both sides of Barry Allen. Sparks fly between Iris and the Flash as he finds a way to flirt without fumbling, and the ever-present warmth between Iris and Barry allows us to see why he would be so hopelessly in love with her. Also enjoyable has been Gustin's chemistry with Danielle Panabaker as Caitlin Snow. In what has been a marvelous move, the show has not spent any time over the first portion of the season trying to generate heat between them. They have been allowed to develop a genuinely loving friendship without a tease of romance to cheapen them into a leg of a triangle. That's not to say that they won't fall madly in love and produce a dozen little genius babies together by the series finale, but the soft touch to their interactions so far has been perfect. Finally, Carlos Valdes has brought a nuance to Cisco Ramon to create in him a character that is humorous without falling into the slot of the comic relief. Sure, he's funny most of the time, but the beats in which we see the serious side to him have kept him from falling into the background.
