Remember “Hannibal”? The one that got away. Let’s not let it happen again.

From what I’ve seen across social media, pretty much everyone who has actually given “The Exorcist” a chance has realized that it’s one of the very best horror shows on TV right now. Admittedly, like everyone else, we had written it off before it ever even aired, but it became immediately clear to us that the show was interested in something more than capitalizing on the brand and making a quick buck. The Jeremy Slater-created series is smart, fresh, and thoroughly compelling each and every week, and it’s been nothing short of a treat for fans of the original film.

Unfortunately, the reality here is that as good as “The Exorcist” is, the ratings aren’t so good. And when a TV show’s ratings aren’t very good, you don’t need us to tell you what happens. With dwindling numbers each week, there’s a likelihood that FOX may pull the plug rather than order a second season… but we encourage you to at least try and make sure that doesn’t happen.

This past Friday night, the seventh episode of “The Exorcist” pulled in just 1.6 million viewers, down from the previous week’s 1.8 million. The steady decline in ratings has been happening on a week-to-week basis, and when you consider that 2.8 million viewers tuned in for the premiere, you can see just how much of a dip those numbers have taken over the course of the past two months. To put all of this into some form of context: at the time NBC cancelled “Hannibal,” another fantastic horror series that pushed boundaries, about 1 million viewers were watching.

So how can you help? Slater has been encouraging fans of the show to post about it on social media as much as possible, and with Episode 8 airing tonight, the fan-driven #RenewTheExorcist is on the verge of trending on Twitter. This is one of those situations where we the fans have the power to keep something we love alive, so don’t underestimate the importance of your tweets.
