The recent crossover between Supernatural and Scooby-Doo was a ratings success, tying with the season premiere for the highest viewership figures of the current run. The appropriately titled "ScoobyNatural" saw the Winchester brothers and their loyal pet angel Castiel transported into the cartoon universe of Scooby-Doo. When the Hunters and the Scooby Gang meet, Dean recognizes the episode they're trapped in and decided to let things play out (and relentlessly hit on Daphne). However, it quickly becomes apparent the the Winchester's world of real-life monsters is bleeding over into the Scooby-verse and the brothers must solve the mystery - alongside their new friends - if they ever want to escape.
Although the episode was distinctly separate from the main arc of Supernatural season 13 and featured little about the ongoing issues of Lucifer's son Jack, oncoming archangel Michael or King of Hell Asmodeus, reviews for "ScoobyNatural" have been largely positive. Critics have praised the unashamedly fun nature of the crossover, as well as the way the very different Scooby-Doo and Supernatural TV properties were merged together.
However, it has now been confirmed that "ScoobyNatural" was not only a critical success, but was a hit in terms of viewing figures also. According to Nielsen (via Variety), the episode matched the ratings scored by the season 13 premiere episode, scoring a 30% increase in its target 18-49 demographic and a 20% increase in viewers overall. In terms of hard numbers, the episode drew in 2 million viewers.
Given how highly anticipated the crossover between Supernatural and Scooby-Doo was, the bump in viewing figures perhaps doesn't come as too much of a surprise. However, the statistics do reinforce the positive fan reaction to the episode, as large numbers of viewers switching off mid-way through would've been reflected in the numbers. Supernatural's producers and network, The CW, took a sizeable risk with this crossover and the idea could've easily been a disaster but with both the reviews and the numbers looking positive, it can now be concluded that the risk paid off.
It's possible that the success of "ScoobyNatural" could lead to more potential crossovers between the Winchester brothers and other classic mystery-based franchises. For instance, it would be fascinating to see a meeting between Supernatural and Goosebumps author, R.L. Stine or Sam and Dean attempting to take down Casper the Not-So-Friendly Ghost. For less childish ideas, a team up between Supernatural and the world of Stephen King seems almost inevitable at some point, and a crossover with The CW's Arrow has previously been mooted.
Supernatural continues Thursday, April 5th with "The Thing" on The CW.
