Strong Pilot episode. While I expect ratings to drop some, hopefully this is a good indication the show will do fairly well.
-sourceTV Ratings: 'The Flash' Premiere Gives CW a 5-Year Best
Don't expect the wave of comic book-inspired TV series to slow down any time soon — at least at the CW. Two years after the successful launch of Arrow, the network premiered spinoff The Flash on Tuesday night. It marked the CW's highest-rated opener since The Vampire Diaries in 2009.
Initial live-plus-same day ratings give The Flash 4.54 million viewers and a 1.8 rating with adults 18-49. Both mark premiere highs since The Vampire Diaries' September 2009 bow. It's even more impressive when looking at the fact that The Flash opened the night, leading into the tenth season of Supernatural (steady and strong for the CW with a 1.2 in the demo). For the 8 p.m. hour, the CW easily outrated ABC's freshman comedies and Fox's animation encores among adults 18-49.
