“The Flash” definitely hit the ground running with its premiere Tuesday night.

The CW’s latest comic-book adaptation, which stars Grant Gustin as the red-clad, super-speedy hero, debuted to 4.54 million total viewers, making it the network’s most-watched series premiere in more than five years, since the season kickoff of “The Vampire Diaries” in 2009.

In the 18-49 demographic most important to advertisers, the “Flash” premiere performed particularly well, especially for the younger-skewing network, scoring a 1.8 rating/6 share in the demo — also a network high since the “Vampire Diaries” premiere.

Across the entire history of The CW, “The Flash” stands as the third most-watched and highest-rated series premiere, bested only by the aforementioned “Vampire Diaries” premiere and the series debut of “90210.”

Overall for Tuesday, The CW averaged 3.66 million total viewers.
