A guest appearance from the scarlet speedster helps Supergirl hit a seven-week high

The reviews for this week’s Supergirl crossover episode have generally been very positive (read my own thoughts here), and preliminary reports show that the stunt also gave the show a much needed bump in viewers.

According to Variety, Nielsen reports that 7.2 million viewers tuned in Monday night, giving Supergirl a 1.7 rating/6 share in adults 18-49, up a whopping 31% from the last two episodes, which were series lows at 1.3. (By comparison, the premiere episode of The Flash in 2014 was one of the highest-rated shows in CW history with only a 1.9 rating. The difference is that Supergirl airs on the higher profile CBS network, where the competition is much harder.)

Grant Gustin’s guest spot also helped Supergirl to win its timeslot among the coveted men 18-34 demographic, beating out FOX’s similarly comic book-themed Gotham and NBC’s ratings juggernaut, The Voice.

Hopefully, the freshman series can continue this momentum for the rest of its season in order to secure a second-season pick-up. Last week, CBS announced renewals for 11 of its popular programs, but Supergirl was noticeably absent. With the large amount of marketing spent on the show and its mostly positive reviews, it seems unlikely that Supergirl will be cancelled, but anything is possible. It can’t be a cheap show to produce, and as the #1 network for more than a decade, CBS has high standards it has to maintain.

One possibility floated by fans is for CBS to pass Supergirl over to sister network The CW, obviously already home to Arrowverse shows Arrow, The Flash, and DC’s Legends of Tomorrow. It’s a move that would make a lot of sense, but would probably result in some big changes for Supergirl. Budgets would need to be slashed, and I wouldn’t be surprised to see the show shift filming from Los Angeles to Vancouver, a move that could result in the loss of some cast members.

Time will tell, and we’ll have the latest news on Supergirl‘s renewal or cancellation as soon as it happens. Be sure to follow us on Facebook and Twitter for the most recent updates!
