It's time to celebrate. The CW has just announced that Supergirl had been renewed for another season. The show will return for Season 4 in the 2018-2019 broadcast season on The CW. Generally speaking, we were confident in the decision by The CW, despite the average statistics of the superhero series. We suggest you read our small forecast on the subject below since it's illustrating how approximately any network regards their television projects.
First of all, let's take a look at the television ratings of the current season. The third season premiere has garnered 1.87 million viewers with a 0.5/2 demo/share (P18-49). This figure is almost 40% lower compared to the previous season's premiere. However, some episodes looked promising, such as 03X08, which gathered 2.713 million viewers with a 0.88 key demo. Despite such an apparent significant drop in the viewership, Supergirl still looks strong on The CW. For instance, these figures are higher than those of Arrow Season 6. Thus, we supposed that The CW wouldn't regard the current season ratings as low. Supergirl thereby stands in one row with the network's other superhero hits.
As for reception by critics and viewers, this factor seemed to be controversial, though it still looked favorable. According to Rotten Tomatoes, the third season of Supergirl has a score of 7.69/10/86% among critics. However, the viewers have evaluated the current season at just 3.5/5 with a 64% approval rating. On Metacritic, the show's score among the target audience is 4.7/10. As a result, the response from critics and viewers hasn't been impressive for this season of Supergirl. However, we couldn't regard these figures negative; they were average instead. An overall score of the show on IMDb is 6.5/10 > 76,000 votes. We believed that The CW would take these numbers into account in their decision regarding the fourth season of Supergirl. It turned out that we were right.
Summing up, we didn't think that all the statistics presented above looked unfavorable. On the contrary, these figures were acceptable for a third season. Therefore, we were inclined to believe that The CW would decide to pick up Supergirl for at least one more installment.
